If i had the money to go with the AFR205's id have them... but my Canfields were $1000 cheaper

Are you talking about these? You think they can outperformed the AFR's 185cc?

I figured that with that mild cam that I have and AFR's 185's should get me a good time N/A...maybe mid 12's or high 12's...then just shoot a 150, to see what I end up with.

i would step up to the 205cc heads. be sure to match combustion chamber with the compression ratio you want.

I have Canfield 205s on my car, they make good power, but all Canfields crack at some point in there life,spend what little extra money it is and get some AFR 205 or the 225 and run a cam in the high 240's and low 250's duration at .050 and what ever lift comes with that and you will be happy.The bigger(reasonably) the head the less cam you have to run to make power.\/\/\/

Do you guys think 215cc Racing Head service heads would be a good alternative, or maybe some 210cc Edlebrock Victor Jr. Heads...Or should I just stick with the 185cc and go with stuff that is proven day in and day out?


Edit just saw the flow chart on the vic. jr's they are the same thing as the 185cc i would just stick to AFR if it came to that...So its RHS vs. AFR right now....

I saw your sig, can you give full mod list of your car and possible track times to see where I could stand compare to your car?

So RHS vs. AFR???

The RHS 215cc are 200 bucks cheaper, than the 185cc AFR...Also they flow better than the AFR's according to the flow charts...But does anyone have any reviews on RHS
