What is the best cheap head for a 70 351W block?

No, they were from a 351. I suspected the roller cam required shorter pushrods. How do you check for interference?

The best way is to put a piece of clay on top of the piston and install the head rocker arm and pushrod then turn the engine through its cycle then pull off the head and see how far down the clay got indented. You need to have around .080 at least to be safe. if you have already torqued down your heads then I would forget the clay part and just install a intake and exhuast rocker and pushrod and turn the engine over to make sure nothing is hitting. I would think that with .472 lift you should be ok though
