COMPRESSION RATIOS - CYLINDER HEADS & SHORT ENGINES
There are various different Rover V8 cylinder heads available, with different combustion giving a variety of compression ratios when fitted to a short engine. Therefore, you will need combustion chamber size of the cylinder heads that you intend to use in order to be able to calculate the engine's compression ratio.
As a general rule, cylinder heads up to the introduction of Series 2 Range Rover (1994) have approximately 34-36cc combustion chambers. From the introduction of Series 2 Range Rover (4.0 & 4.6 litre engines), they have approximately 28cc combustion chambers (If in doubt, cylinder heads fitted to 4.0 & 4.6 litre engines have only two rows of cylinder head bolts; earlier engines have three rows).
Refer to the table below of Short Engine & Cylinder Head Applications for more detailed information.
This information does not take into account any machining work done on the cylinder heads in the past.
In certain circumstances, it may be cheaper to purchase a pair of reconditioned cylinder heads than to try to match a pair of unknown heads to a Short Engine.
Alternatively, it may be worth considering a Full Engine, which is supplied complete with fitted cylinder heads.

Stroker Kits These kits enable you to enlarge the cubic capacity of your existing engine by increasing the stroke, hence the name 'stroker'. The kits comprise a brand new, high quality crankshaft, conrods and pistons (with bearings and piston rings supplied). The stroke is increased from the standard 3.5/3.9 engine’s 71.1mm to a massive 86mm, (longer than the standard 4.6 litre stroke of 82mm) giving a capacity of 4.3 litres on a 3.5 engine and 4.8 litres on a 3.9 engine. Both engines require a 20 thou rebore before fitting. Finally, a small amount of grinding is required to the bottom of two cylinder liners (full instructions supplied) to allow clearance for crank rotation. The result of the extra stroke is a huge increase in torque, even on an otherwise standard engine. Alternatively, you have the basis of a high performance engine, to which you can add our fully modified, big valve cylinder heads, uprated camshaft and sports exhaust system. If you would prefer, you can send us your 3.5 or 3.9 block and we will do the work for you. Please contact our sales department for a fitted price.

Oil Pump & Filter

Oil Pump & Timing Cover There are two types of oil pump for the V8 engine fitted to the Discovery. The first was fitted from 1989 to VIN LA (approx. March 1994) and is a camshaft-driven oil pump, incorporated into the lower right hand of the timing cover, with a removable housing for the relief valve and oil filter. From VIN MA (April 1994), the oil pump was changed to a crank-driven type, incorporated into a redesigned timing cover without the need for a separate relief valve housing. The two types are not easily interchangeable, as the later design requires a longer crankshaft nose to accommodate the oil pump gears.

Cylinder Heads - Standard

Cylinder Head Identification
There are various types of cylinder heads available for the Rover V8, with only subtle differences between them. Not all are suitable for every application, so care must be taken when ordering replacement heads for your vehicle. Please note that reconditioned cylinder heads are only sold on an exchange basis (in pairs) and that we require similar type cylinder heads in return, otherwise a surcharge will apply.
Early Cylinder Heads
Early cylinder heads - as fitted to Rover P5B, P6, MGB V8 and early Range Rover - are fitted with small (38mm inlet, 33mm exhaust) valves and may not be suitable for use with unleaded fuel. These heads can be identified most easily by removing one of the spark plugs and measuring the length of the threaded section of the plug. If it measures 12.5mm, the cylinder head is an early type and is not suitable for exchange. If it measures 19mm, the cylinder head is post-1976 (SD1 or later).
Later Cylinder Heads
Identify later cylinder heads as follows:
1. Count the rows of cylinder head bolts. All cylinder heads have a row of head bolts inside the rocker covers; they also have a second row of 5 head bolts just below the spark plugs. Finally, cylinder heads up to around 1994 have a third row of 4 bolts just below the second row. 3.9, 4.2, 4.0 & 4.6 litre engines after this period have a total of two rows of head bolts.
2. Look at the ends of the cylinder heads, as fitted to the engine. There are tapped holes in the ends of each cylinder head, to which the ancillary component brackets are bolted. The number of holes determines which type you have, as follows:
   3/3 bolt (3 bolt holes in each head)
   3/4 bolt (3 bolt holes in one head, 4 in the other)
   4/4 bolt (4 bolt holes in each head)

It is important that the cylinder heads you order are similar to the ones you have removed, otherwise your ancillary components may not fit.

Head Gaskets

Composite Head Gaskets The advantage of using composite gaskets is that they provide a superior seal compared to tin gaskets. However, composite head gaskets are thicker than standard tin gaskets and therefore have the effect of lowering the engine's compression ratio when used as a direct replacement. To calculate their effect on your engine's compression ratio, see the figures below. Other factors which influence the compression ratio are the size of the piston bowl and the combustion chamber in the cylinder head, as well as the amount of material which may have been 'skimmed' from the head faces. Removing material from the head and block faces in isolation will not compensate for composite head gaskets and may lead to inlet manifold alignment problems. Approx. thickness: Standard tin gaskets 0.5mm Composite gaskets 1.2mm Typical effect on compression ratio: Standard tin gaskets 3cc Composite gaskets 10cc

*Composite head gaskets are thicker than standard tin gaskets and will therefore lower the engine's compression ratio. Ideal for correcting compression ratio when heads/ block faces have been skimmed. (Not applicable 1995 on).
Approximate gasket thicknesses are as follows:
   Standard (tin) gaskets 0.5mm
   Composite gaskets 1.2mm
Typical effect on compression ratio:
   Standard (tin) gaskets 3cc
   Composite gaskets 10cc

Cylinder Head Bolts

All engines up to 1995 (except late 3.9, 4.0 & 4.6)

Long (7/16" UNC x 3.9") - (6) - 602193A

Medium (7/19" UNC x 2.7") - (14) - 602192A

Order 13 if your engine has a dipstick retainer clamp on the head bolt adjacent to the dipstick.

Tapped Bolt (7/16" x 2.7") - (1) - 602450

For dipstick retained, if fitted.

Double-Ended Bolt - (1) - 602200

Fitted to some Range Rovers.

Short (7/16" x 2 1/4") - (8) - 602191A

1995 onwards (late 3.9, 4.0 & 4.6)

Note: These bolts can be identified by their flanged head. They do not need a separate washer and can be used on earlier engines.

However, they are not re-useable and must be replaced once removed.

Long (96mm) - (6) - ERR2944A

Medium (66mm) - (14) - ERR2943A

Note: The outer row of short bolts, or 'outrigger' bolts, has not been used since the introduction of the Series 2 Range Rover.

Engine set of ARP cylinder head studs, washers and nuts to replace original bolts. Studs improve cylinder head sealing & prevent damage to block threads.

Rocker Gear

Lifter Preload Lifter preload refers to the position of the pushrod seat in the lifter (cam follower) when the engine has been assembled and the lifter is positioned on the heel of the cam. Lifter preload must be checked whenever a non standard component which alters the distance between the rocker arm and the lifter - such as a high lift camshaft or performance cylinder head - has been fitted. Incorrect lifter preload will cause poor running, premature wear or, at worst, engine failure. Check the lifter preload as follows: With the lifters empty of oil, assemble the rocker shaft & pushrod components, making sure there is no wear in the rocker shafts, rocker arms & pushrods. Checking each lifter in turn, positioned on the heel of the cam, measure the gap between the pushrod seat and the bottom of the circlip groove. There must be a clearance of .020" minimum and .060" maximum at this position. If the clearance is greater than .060", use pedestal shims (603734SH) to decrease. Remember to use equal thickness shims under each pedestal of a shaft to avoid distortion or breakage.
