Well, while installing my AFPR today I discovered the dreaded manifold oil leak. I figure I'm gonna yank my manifold and then the heads. Get the heads ported, change the gasket to the Impalla SS type, reinstall everything and see what happens. Saddly my budget does not allow for CAM or RR yet.

How much HP gain would you expect with ported heads and no RR or CAM work. Also, I haven't smogged my car yet. Will this effect my my emissions? Given the lift is the same I would think it woudn't have any effect on emissions.
