Now I Need Help!
I pulled my L48 part, found the cam with wiped out lobes. You know where it went. Brought the short block to the machine shop for bearings and rings. Well I need new pistons and crank cut. 355ci. is coming.
Well here is my problem, I purchased all the top end parts. I have
Edel heads w/64cc chambers, with .015" head gasket to get proper quench @ 9.5:1 comp. w/12cc pistons, and .027 in the hole. will have deck milled a minimum.
Options are: 10 or 11cc dish pistons and use .015" head gasket or
get 5cc flat tops with .038 head gasket, will boost compression but will also increase the deck to about .061" more quench. Want to run pump gas. Cam is 219/227-112 Adv. Dur. 262/268
I'm looking for some experienced advise, Thanks

Thanks again. I went with the 5cc flattops and the .041 felpro head gaskets. That will bring my compression in at 9.7:1 Static & 8.1:1 Dynamic which is good for me. The only thing I'm worried about is the quench @ .068. Do you like I'll get ping! ping! on pump gas 89 oct.
