No. We got the other head off Friday only to discover that, while the pistons being well used would work fine, theres a small chunk missing from one. I proceeded to curse alot, then decided to take my large prybar and go apeshit on a busted TV we had, and consume a pack and a half of Camels. I busted my ass in the heat for 5 days, got cuts, scrapes, banged up knuckles, a chemical burn from freon, and then I find that screwed up piston.
