I saw the Forum
about the Best Gaskets,and my take is as follows. I have had Blown
Fire Rings on a number of the Gaskets on Iron and Aluminum heads. But not
on the old style Metal Sandwitch type. If you look
very close to the Fire Ring and the very Small and NARROW Fold they have
clamping force on the Composition and the Fact that if you hold the new gasket in
hands you can Move some of the so called Fire Ring from side to side a
The Ring is not
wide enough, then look at one of the old style Metal type ( Fel-Pro)
or Victor and you will see that the Fire-Ring is Part of One Side of the metal
gasket and it is folded over by machine and becomes the Ring itself. This makes the
Ring very strong as it is part of the make up. The head
and Gasket will move a very small amount under power That is why Manufacturers
of Engines do not install Dowells to block to Cyl heads.
a Best Gasket with 1/2 holes and Aluminum head 7/16 to Distort and actually
elongate The Fire Rings on each cyl. with not to many Miles. ( the 1/2 inch
holes let the gasket move over till the 7/16 studs touched the holes in the
gasket. It was torqued to 65-70 ft lbs ) He now uses the
metal gasket on Hudson Aluminum heads with No Gasket failures.
4-5 308 best head gaskets for sale and Very cheeeeep
The 46 Hudson has a Turbo. and I use the aluminum 308 cyl head 0.40 over and with only 7 lbs of
boost with 75 ft nut torque on cyl head and so far it has lasted 3-4
years with steel gasket. ( i hope it lasts much longer as it is my Every

Freezing days )
