Valvetrain setup...PAC 1221 questions I'm switching from my PRC duals to PAC 1221's. The Pac's ID is .655...so will the LSx Valve Stem Seals, .500 X 8mm be ok?
Also, are the 1221's just drop in springs with the new seats they come with?
thanks in advance

I think those should be OK. And I believe you can just drop them in with the seats they come with. You will need to check the installed height of the springs. They may need shimmed up a little.
