Hey Loz. Keep it nice and simple on the head. All the lads I no at Mascrat running 500whp are either running the Tomei Pon Cams 260 9.15, HKS 272 8.7 and 1 guy is running the Jun 272 (not sure on lift).

You dont need to do anythink to the head expect for cams, metal gasket and a service. Im also fitting new bronze valve guides to be sure on reliability.

You can go up to 10mm lift befor you need serious head work and the Tomei's @ 9.15mm are the closest i've seen and thats what i'll be fitting.
Also i've been told it may be wise to fit some kind of oil drain on the back of the head! But will have to double check on that.

Loz, have a look at some of the threads on Octane Junkies. Were starting to talk technical about the engine rebuilds. Also i'll be buying alot of bits in the new year so maybe we could sort somethink out about getting hold of them cheaper.
