Turbo vs heads
Turbo vs heads OK Guys I'm on a budgit and I realise I can either finish my engine with all the good parts in it and have weeker flowing heads or I have to hold my project off to next year.
I know that the more your motor makes the better and more HP you get with boost but this is my question...
Can you make good power like 700 whp on just ok heads... It is forced induction right?!? wont it just push the air through? So isnt putting big money into heads just a nice thing to do not manitory?
My set up is a 383 lt1 Diamond 4.030 Bore/3.750 stroke/6.00 rod -18cc dish 9-1 comp pistons my cam specs are 228/232 560/560+115 @ 1.6 rocker ratio I'm using a turbonetics 76mm turbo with a .81 ar. "yes I know the AR is a bit small but I think it will still work.
Can I get away with for this first year stock heads or stage 2 port heads? then next year use AFR's? once again the goal is 700whp

You can definitely hit it with heavily ported stock castings (what you call a stage 2) or aftermarket heads (such as ported AFR's).
**Note** It will not hurt your engine to run it with stock heads... you will just have to settle with less power for now.
We need to make the kit... I just have the turbo and a tail blow off and waste gate
I'm building the motor. and a have a a1000 fuel pump with -10 lines
I dont know what intecooler to go with.

I don't see why you can't hit that goal with mildly ported stock castings.

This was done with a smaller cam than yours and it was done with a Procharger on 14 psi. With yours having a healthier cam and using a turbo you don't have the parasitic loss of a blower, it can be possible on stock castings.
