afr 165 vs performer rpm

I've had a set of afr's and it looks like I've screwed'em up enough that its gonna be cheaper to get new heads. Will I see the same power with the performer rpm's? Or would you recommend repairing the afrs for $800!

warpped all exhaust valves over-revving and wore the guides using too long pushrods the past three years. Two hundred dollars more for the performers....

to much air flow will kill your torque is what ive heard.but on a heads,cam,intake car the afr heads are going to pull away from the edelbrocks.this is box stock to box stock.
