Fair play for actually wanting to read comments and learn!

there are only a few peoples opinions on here that i personally would trust though, there are LOADS of clever people too, but only a certain few who i'd actually trust to work on my own cars and believe what they tell me as fact...they are;

Karl Norris
Stu
Mark Shead ( as long as his runt is nowhere to be seen )
Tony Turbosystems

As for what i disagree with, the first part about comp ratio...there's really no need to worry about it at those power levels.

Your other comments are kinda right, although it depends what parts are fitted to get a standard head to make 400bhp...i've personally never seen a T34 do it anyway.

Don't take my ramblings as fact though whatever you do!
