rebuild 502 mag heads??
ok, if I pull heads out to have rebuilt and have rollers installed what type h.p. gains can I expect? Also is there any way to replace cam without pulling engine out to have the room on 27 fever? I already have stainless marine mainifolds on and seeking maybe 50-75 more h.p. any suggestions race fans?

Probably about 30 Hp for the cam change. A fresh valve job may regain some lost HP, but it won't add anything without some port work. Mill the heads .030 and up your compression to about 9:1 and gain maybe another 10hp.

what if i had the rollers installed on the heads and port/polish work what do you think I can gain h.p. would i be better switching to new dart performance heads? would this require additional mods?

alum heads are your best bet,,,, plus you eliminate the exhaust seat issue of the cast heads with the new oxygenated fuels.
