allen head bolts?

While the tensile strength may be stronger, translating the torque into clamping force might be slightly different.

I agree

I can tell you from personal experience on my old 5.9

Careful, you are starting to sound like one of those snooty 6.7 owners!

I was thinking the same thing........

O hell....it ain't no 6.7 thing....I was talking a while back about milkin' more miles out of a head gasket and Snedge talked me into just doing it. Very glad I did once I saw it.
