A little advise

Actually the pistons aren't much different in price. In this case, they are cheaper.......

Those are low compression (way below deck), dished, with no valve reliefs. So yes, they can be gotten, but no, they really aren't performance type deals. That's why I'm leaving the lower end in mine alone. Too much cash for real pistons if the others are decent runners now.
