£450 +VAT

Using your own supplied cylinder head and off-the-shelf valve guides.

If you require Trojan guides add £300 for 8 fitted and honed to size.

Trojan is a higher quality material which handles heat better and reduces the amount of wear which takes place. They are specially made to order then honed to a precise fit hence the price.

The cylinder head pictured, along with other parts from this page recently made 485 bhp and an incredible 454 ft/lbs (616Nm) of torque on an engine dyno.

Tip:

If anyone is going to port your head then ask them about cylinder swirl, what it does and how these heads create it, if you are going to port the head then ask yourself the same question and how easily it can be ruined. If blank looks are all you see then tread carefully. All my port shapes and modifications are the result of many hours spent on the flowbench and retain this feature as it is a very important part of this cylinder head, many people don’t even know it exists.

Vernier pulleys: £210

High lift cams: £470 per pair (x2)

Various profiles and prices are available from mild to fast road, full race or even Group A spec.

We do not use standard off-the-shelf profiles as they have proven to be much less effective than a specifically designed one. You can read about cams here:

Cometic head gaskets: £140

A thoroughly modern gasket, throw your old composite gasket in the bin where it belongs. All engine manufacturers now use MLS gaskets as standard, HG failures are largely now a thing of the past.

Modern diesel engines typically run a static compression ratio of from 15 up to 22:1, then they are pressurised even further by the turbo. They use multi layer steel head gaskets as standard and do hundreds of thousands of miles with no problem. This is the main reason I use nothing but Cometic MLS, there just isn’t anything out there which is as good, we do not get failures caused by these gaskets.
