SM Head Install... forgetting anything?

@plumkrazee70 my pistons stick out .012-.013 from the block. Regarding the heads being closed chamber or not... I have no clue?? Lol. I know they are eddy knock offs... I think? Some people run thinner gaskets to change compression ratios, but that requires decking the block and heads... really thats way out of my realm of knowledge as well.
Felpro 1008 is .039" compressed thickness.You say your pistons are .012" to .013" out of the hole. That's. 026" squish on a closed chamber head. Seems a little tight to me.
