Well, I'm kind of deciding whether to throw my Indy SR heads on that are ready to go with roller springs, or throw the untouched Pro Comp Victor copies on but change the springs.

I'm thinking the Max Ported SR's are a little big for the 440. The Pro Comp 265 cc runners should work well so it's a matter of having the time to do it.
They are going in my 72 Duster.
