how much cam with performer rpm heads?

Kevin D. said
I am faced with same dilema have eddy heads really dont want spend any more on them other than mild port and gasket match. I believe I will run the .525-.525 solid lifter comp cam. I hope the springs that come with the heads I believe they are #5767 will support this cam.Thanks Kevin.

i talked with eric at muscle motors and i mentioned the comp 250 .525 110 solid cam and he said those springs would probably be ok for it. he said those springs are 130 on the seat and that he recommended their edelbrocks that have 10deg locks and a 5 angle valve job= 18xx.00 bucks. thanks for those links!

Hummm, strangley, I have the same lift cam but the duration is 248* @ 050. Reguadless, I have not yet opened it up for a run. I think it'll be OK since the spring pressures of the Edelbrock heads and the recomended one via Comp Cams are close.

This is half the issue. The other half is total lift of the cam. Kowing the springs are goof for a .575 lift, then yeilding before that is good.
