oem compressed head gasket thickness on a 360la?

I have a mopar performance short block p4876907 witch has a dech height of 9.56" and heads that i'm guessing have been milled .010 they are 71cc combustion chambers (had them cc.d) I do not think the intake side was milled, I am going to use a felpro 8553pt head gasket, I am new to this and just trying to figure out if I should mill the head intake side .0095 and was trying to make it work using stock push rods with stamped rocker arms and rocker shaft shims.
I was wanting the pan rail to intake rail measurement to check to see if mopar milled it when they decked the block.
