NEW BLOCK WHAT HEADS

[ph4926]

Ok guys I just got a great deal on a mach 1 alum shortblock for my 96gt what heads would you use?
4v with p&p and cams?
2v pi with p&p and cams?
I would kinda like to stay 2v but would I make much more power with4v?

power

4V heads flow alot better than 2v heads I read somehwhere stock they flow 260cfm and ported can flow over 300cfm,but if you build a 2v with like stage 3 p.i. heads they flow around 250cfm, and with the right parts you could build a nice motor.

heads

I would also check what the compression ratio would be im not sure the combustion chamber size of the 4v heads versus the 2v heads.

cant beat the sexy 4v....

if i was doing a modular, 4v would be the way i would go

heads

I looked up the 2v head versus the 4v the 2v p.i. had 42cc and the 4v heads were like 51 cc from 99 up so if you used 2v heads you would get a hike in compression not sure how much though.
