Milling edelbrock small block heads

[345man2]

hey guys having some combos run through my head , how much can you mill a set of the closed chambers safely, and how much = a cc?

.006 per cc of chamber volume reduction.( Example .030 milled is a 5cc reduction.) I've milled SB Chevy heads down to the valve seat inserts, pretty common on late model SPEC head engines with over 14:1 comp. Don't see why one couldn't go that far on a SBM Eddy head. How much milling that would take I don't know.

thanks i wonder how many cc's is the max?

Not sure how much you can mill...but mine are milled down to 57 cc combustion chambers and it looks like there's a little bit of room to go still.

Mine are milled to 55 cc combustion chambers. Heads are milled 0.60.
