hope someone has some light to shed on these pistons. i have two sets. but one set is pretty well screwed (person overheated the engine and welded the piston rings to the cylinder wall, as well as scraped the bejeezus outta the pistons).
btw danny, sorry to hear about ur block thats a bummer man :/
