The Indy TA heads work well with hyd. rollers, as well as the edelbrock magnum heads if you want aluminum....the TA heads can make it OOTB if you have a large enough cam...otherwise some port work is necessary. The magnum heads will require mild porting to get 500 with a normal size cam (236@ .050). I like the magnum heads because of the cheaper stud/guide plate arrangement but that's just me...they make good power per cfm of airflow too.
