[Fot] Best head gasket revisited

[Tony Drews]

I use the Cometic 91mm gasket.  I've purposely NOT taken more out of the 
intake pocket since it already goes way outside the bounds of the liner 
- I just took the sharp edges off to keep from getting a hot spot.

The Cometic does intrude into the combustion chamber next to the intake 
valve but not by very much.

I also make sure to not relieve the liner outside the bounds of the fire 
ring in the gasket so it's supported on at least one side and can pass 
the heat to the liner.  I don't blow head gaskets, but I also don't run 
one for more than 2 seasons, normally for just one season.

Regards, Tony
