have a set of edelbrock RPM heads with stud mount rockers, i was looking in the summit catalog and it says 80 and up 5.0 blocks, any one ran these heads on a 68 block( or earlier than 80), what problems occured? thanks guys
you can run them on the early block, I would just make sure the water passages (holes)are right sometimes they have to be drilled in the head to match early blocks, other than that depending on the cam you may have to fly cut your pistons.
