next?

If I had your setup I'd put some headers on there asap, I'd just want to see the difference. They'd have to help.. it seems to be the bottle neck at this time.

I have to wonder if a cam will make the 1.72s tap the valve covers. I'd probably get a cam but make sure I had enough $ left after all mods to get valve covers if they are needed.

Hmm.. a bigger maf would probably help as would porting the heads and intake. I agree with the others, those heads and intake still have alot of miles left in them.

Oh and a blower would be nice, of course.(maybe down the road?)
