Showed a great increase of power using roller tipped 1.6's, after that they gained an extra 1 hp form going to full roller rockers.
Still the 1.6 roller tip rockers are what im getting not much price difference,I think I need stud mounted ones, but do I get the 3/8 or 7/16 ones.
& what about self aligning is that important?
