any one had experience with 4.625 bore as it relates to head gasket sealing ? n/a 10.5 static less than 6000 rpm

I see that fel pro is making a multi layer like the cometics, I have been running a standard fel pro at 4.6 in the boat with no major problems, I believe it is right on the edge of sealing at the bridges. I dont run alot of rpms, but I do sustain wot .thanks for input.

Fel pro has the 1077 MLS 4.640 bore.
