RPM performer heads w/2.02 intake valves ?
How much power would the RPM performer heads w/2.02 intake valves, heads give me (guestimate), if im running gt-40 upper and lower, on a 10.5.1 motor, over my old gt-40 alum. heads ???
i found a pair for $800 bucks brand new with 1.7 svo rockers

I would guess maybe 20ish hp max. The eddy heads just aren't that great.
I think the $800 would be better spent in other places. -Josh, aka the tireburner

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).  Quote:
 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. |
