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?
