hard to find a head thats too much for a blown stroker, why do you ask?

Someone had told me that my combo may be better with a smaller head. Maybe he just wants the heads I am running [Smile]

Those heads are going to be a little much for that combo...but don't trade them just yet...especially if that someone wants to trade you Victor Jr's...

that blower is going to want to move air. shaft rockers, im assuming solid roller lifters and a big cam since you posted .600 lift cfm. if you plan on taching over 6k and want to make big numbers on top, keep them. if you want an ubertorque low rpm big rig, then yes, smaller. DONT spend any money changing them

the heads are only going to flow as much as you put thru them. if you are worried about low rpm power, ditch the heads. if you're not(and i doubt you are), keep them
