u would notice the most gain on an engine with awsome flowing heads. i would recommend aluminum because they run a lot cooler an u save weight over the irons. some good companys as u prolly already know is AFR, trickflow, edelbrock, canfeild.. just to name a few. once u know what heads ur gonna run with pick the cam size according to how the heads flow.
