TR5-6 and 2.5 PI etc. Fast Road unleaded cylinder head with bronze guides for unleaded use. All new improved valves and springs are incorporated whilst using existing caps and collets. Aluminium caps can be used at extra cost. This head is offered on an exchange basis or the work can be carried out on your cylinder head.

A deposit applies until a suitable head is returned to RevingtonTR. The full range of 6 cylinder heads are listed below

The engine is in effect a pump inducting fuel and air and exhausting waste gasses with a restrictor valve on the inlet and the outlet. If you increase the effectiveness of the pump (an improved cylinder head will increase the effectiveness of the pump) then the restrictor valves will need to opened up so more gas can get in and out. The inlet restrictor valve is the combination of the air filtering system, the metering device (PI metering unit, Electronic fuel injection or carburettors) and the outlet restrictor valve is the exhaust system. The effect of not addressing these issues will be that the benefit expected from the improved cylinder head will be much reduced.

On the inlet side the air filters must be large enough the pass the required air unhindered and the inlet manifold should be cleaned up inside and matched to the cylinder head inlet ports for best results.

The exhaust is simply dealt with by fitting our extractor manifold and exhaust system RTR2042 which has shown on the rolling road to improve power output over a standard system, with a good head fitted, by 25BHP.

This brings us to the last important issue. Best results for the whole package will be achieved by visiting a reputable rolling road operator and having the fuel and ignition systems tuned to this entirely new and quite likely unique engine set up. Remember an engine begins with the air filter and finishes with the exhaust tail pipe. All the relevant parts in the middle need to be in tune with one another. For those in striking distance of Revington TR, we have an 800BHP rolling road and can undertake this work for you.
