Do any of you guys know how much horse power there is to be gained in
porting a set of heads? I have a set of oval port cast heads off of a 454
that already has had the over sized stainless valves installed. I'm
putting this 454 in my 68 SS Chevelle. It's got a 400 turbo trany with
with 308 gears. Just wondering if it's worth the extra cost while I have
the engine apart? Thanks ahead for any help you can give me on
this....Dennis
