Cheers Guys!

looks like the 272 H10 (the last crane cam from techinspector1 - cheers) is what im looking for. just seems to have a much better top end with only a little sacrifice in idle etc. duration looks fine. prehaps 1.6:1 rocker ratio on the exhaust valve to improve lift?

As for the manifolds, looks the Perfoprmer kicks the RPM's ass for torque, so ill prob go for that. has anybody tried the performer air-gap or the performer EPS???? is the air gap woth the extra 100 bucks?

vortec heads would be nice but probably a bit pricey (plus having to buy special manifolds etc). IF i had a bit extra to spend, what would people recomend to buy...

full roller valve train (so higher lift cam can be used)
OR vortec heads with a standard valve train??

maybe just sell my kidneys and buy a supercharger..... mmmmmm
