Default What will I gain??

Right now I have PRC 5.3 Stage 2.5 Heads on the car. Thinking about going to a TFS 215, ETP 215, PRC LS6 stage 2.5, AFR 225 small bore or something similar. What do you think the gain would be over the PRC heads? I am not seeing much cfm difference on any of the heads. 12 cfm tops. Thanks for any help.

what are the rest of the engine specs? cam? intake?

my guess would be 10-15hp peak, and likely some power in the low/mid range as well.

why not the AFR 205s? they are a GREAT street head. not manny use the 225s on stock cube setups

Grab the TFS 215's and dump that MS3 for a custom cam that will tie the entire combo together. Your cam should match the flow characteristics of your heads.

I'm waiting to get more info on the new AFR 215's. Tony put up a thread the other day about testing/dynoing getting ready to start. That's the way i'm leaning.
