These are the same rockers that came on the alum headed crate engines....so yes they will work fine.
With a large cam, converting to pushrod oiling or improving the oiling is needed to prevent burning pushrod ends.

I'm using cast alum Mopar covers so dont know for sure but I think these will fit under stock covers.



I think the cam lift is .557 intake/.540 exh , it's a solid cam, these really came on crate motors? Dick landy stainless rollers? What is the difference between a set using "collars" on the shafts, and others use springs? Is one preferred over the other?
