Thanks John,

I'll be pulling the heads Friday and hope to have most of the measurements complete by Monday.

My mistake...it was a .040" Fel-Pro gasket I used, however I did find the following compressed head gaskets for a 4.380" bore between Summit, Mancini, Jegs, and 440Source;

Mopar Performance
P4286754 - .020"
P5155237 - .025"
P4349559 - .040"
Cometic
C5461-027 - .027"
C5461-040 - .040"

Many selections above .040" between Mopar, Fel-Pro and Cometic if I need to go there.
