I think what you'll find is , that with only a 4.166" fire ring diameter , if there is any variation in bore centerline , or dowel pin placement , you'll have part of the fire ring hanging in the bore . Also , getting high compression ratio on a 400 is not a problem , so gasket diameter and thickness is not as important as with a smaller cubic inch motor .

They do Ferrea part # G50021 4.065 bore x .035 thick we use them all the time.anything smaller may be a problem in a block that hasn't had the bore centerlines corrected.its better to be a little large than to have the gasket hang in the bore.

Also, Felpro makes a 1043 head gasket with a bore of 4.080. I use it on my 350 blocks.
