AFR heads Vs Edelbrock Performer RPM

White 89 · July 12th, 2010, 10:00 AM

which would you choose and why?

for a 331 stroker. We used Probe industry engine kit. Now its time to by heads.

Keep in mind its going to be a daily driver. Will be carb set up. manual trans car 3.55 gear.

There's not even a question....AFRs. Performer RPMs are not not much of a step over stock. They don't even compare to the AFRs.

afr...

White 89 · July 12th, 2010, 10:18 AM

I'm looking at AFR 165cc or AFR 185cc street port heads

and Performer RPM's are not a notch above stock. They actually show good flow numbers way more than stock.

I didn't say they weren't better than stock. I said they weren't much better than stock, and they aren't.

I'd say TW 185s or AFR 185s.

If you're going to shell out the cash for a brand new set of aluminum heads, they're just a poor choice to spend your money on. They have the stock valve location, with small valves, poor intake runners, and poor exhaust runners. Why spend the money on a stroker kit, and then put a set of marginal (at best) heads on it? You'd be better off to not stroke it, and put a really good set of heads on it.

White 89 · July 12th, 2010, 10:47 AM

STREET CAR.......FULL TIME STREET CAR daily driver.

Spike Digidy! · July 12th, 2010, 10:48 AM

im not 100% sure but i believe the afr has stock loacated runners, id shoot for a rpm air gap, but u might wanna consult sum 1 who actually has them heads to verify

93hatch · July 12th, 2010, 10:51 AM
