Attaining most p-v clearance, questions
« on: April 25, 2009, 02:16:39 AM »
i recently purchased a ported head. long story short, its been milled to shit. im looking for my thickest base gasket/head gaskets.

im going to double up the base gaskets with some copper seal. from what i've read briefly, the oem stuff seems to be the thickest torqued?

what is my best option here? i havent gotten it to clay yet, but im not real optimistic at the moment.

Clay it up and do a quick assembly on it and see how much clearance you have. You need .080" or more P2V clearance. Stacking base gaskets and/or running thicker head gaskets will help this but hurt quench on the chamber from the piston and power and effeciency will suffer. Stacking base gaskets doesnt require a sealer since theres not alot of pressure there to cause leaks- I know of one guy that forgot to put his on and didnt realize it until after it was runnin when he seen the pack on the table lol. He asked me about it and I asked him if it was leaking any and he said no so I told not to worry about it unless it starts to leak. He called me over a year ago I guess and I havent heard any different from him. I dont rcommend assembling the engine without it on purpose though lol.
