intake milling
I used this time and time again-
http://www.mopar1.us/mill.html
and it's always been on.
btw most performance intake gaskets come out around .060 thick each.
victor and felpro, and some other company that makes the 'other' black mag int gasket sell .030 thick intake gaskets.
I try to stock both for occasions like these, I ended using a .030 on the 410.
you guys can also shim the head up, measure, then use the formula that way.
