Mild 351 - what heads?

Simple (foolish?) question here... what do non-stock heads give you?

I'm looking at rebuilding one of my 351's, and I figured I'd try to get it running efficiently on gas, yet still have "fun" power. Would changing the heads make a difference in this area, or not enough of a different over stock heads?

Re: Mild 351 - what heads?

Depends on what your after. In mild combo's the 302CC heads are good. Then if you have more $? Edelbrock, CHI and AFD all have cylinder heads that will control detonation better, disperse heat faster , have a better torque curve and consequently make a little more power.

What kind of gains did you make? What heads were you running previously?
