Thanks for the help with this guys

Nothing wrong with a standard head but it is restrictive and that is why peek power is made at around 5500rpm, your 285T2 will help a little though.
Also you have to remeber that boost pressure is relative to the VE of your engine, if for
example your running stock head, cam, and T3 you may make 200bhp @ 17psi, but if you then run a ported big valve head, a 285T2, and a Stage 3 T3 you may make 200bhp @ 10psi
The pistons will take a certain amount of power
not a certain amount of boost
