ok, i know this has been asked a million times,i have a set of pi heads w/comp cams 270's and bee hive springs now i was thinking of getting the heads ported and polished. i waunt to keep it street worthy i would be interested in seeing what you think about how much more power that i might be able to gain from porting my heads. i'm also running a low boost supercharger 6 lbs. so please tell me what you think and also how much might this cost(the heads were just done over and have not been installed as of yet) i just hate to install them not ported as long as it's not to much $$$. thanks for your input.
