RPM performer heads w/2.02 intake valves ?

[ultraflo]

Depends on which part number they carry... if they're the 6025's then you'll pick up less HP/TQ compared to the 'new' 60259's which utilize revised (improved) combustion chambers, intake and exhaust ports, etc.

The RPM's are better than the GT40's ...but not by a huge margin by any means, but they are better.

What camshaft do you use? Josh makes a good point, in that the money could be better spent elsewhere. Maybe some good axles and a locker, for starters (looking at your sig).

Hey, now don't be knockin' my home-ported 6025's Josh! I'm gonna see just how much power I can (or can't, LOL) squeeze out of them before stepping up to something more serious.
