I'm looking at a 402 with all pro heads. I found a set of 317 heads with 918 springs for real cheap. Could i just pull the all pro heads off and slap the 317's on or is there more to it than that? I'm sure the all pro heads are great, but, if i can sell them and if the 317 will do the job, why not? I'm told the all pro's are like $3000. Would the 317's be good enough for that engine and a whipple supercharger?

the 317's will be alright and work desent but the allpro heads will be great and super.
if your power goals are small then yes your money could go else where

i'm pretty sure whipple can only make 600rwhp no matter what heads are on it. so, yeah, my goals are "small".

I would agree with your idea. The whipple could turn slower to make the same boost # with the smaller heads.

Then again I may be wrong
