80-90 roller 360 question

The heads will bolt on except you will not be able to use the roller cam without opening up the pushrod holes on the non-roller heads. The roller motor had larger pushrod holes in the heads. You have to be careful opening up the non-roller heads so you don't go into the intake port. If you run a flat tappet cam in the roller block then you can use the non-roller heads as is.
