More power derived from swapping heads or cam in forged 347 LS6 D1SC Blown?
Title says it all. If i were to keep either my stock lS6 cam or heads in my future forged 347 LS6 motor running 14 lbs of boost with my D1SC in my 02 Z06, will i pick up more power throughout the entire rpm band by swapping out my heads (and keeping stock cam) or swapping out cam (and keeping stock Z06 heads)?
I know swapping out both would yield the most power but if you were going to only swap one out, which will get me down the 1320 (1/4 miles) quicker?

Im gonna say the cam for sure. Since you are forced induction you dont have to rely on the heads as much in terms of velocity but with a bigger cam you can really fill that cylinder with alot more air if the valves stay open longer. I would also stay with a 114 or higher lsa. Dont want to bleed off any of that boost.

Anything that helps airflow is going to make more power...It works the same way as an NA setup except the proper cam for you will be quite different and will affect your power much more than the heads.

That being said, several other guys said the exact oppossite thing last week and that the HEADS would yield more power so just doing a little more double checking b/f i conclude my research on the issue set forth in this post and before i order my blower cam 224/230, 114 lsa (+0 advance), .581 lift i am thinking!
By the way, what to you guys think about that cam running 12 to 14lbs of boost on my D1SC powered LS6 motor with stock heads and dual valve springs of course!
