I got a spare cylinder head a few months back with the intention of playing, well a few weekends later these are the results.

I'll hopefully be swapping the heads over next month, then it can go to the same rolling road that has tested the engine in the past, it'll make the comparison have a little meaning.

Well, £100 of work and parts and £140 for the rolling road got me 7hp and 15ftlbs extra. Strangley to extra torque came in a 400-500 rpm rev band. Anyway a bragsheet for you all to pour scourn on

Looks good Dan.

I'll stand no chance of keeping up with you when I finally get on another track day!
