double gaskets

[britcars@juno.com]

My MGA came with a head that had been  "shaved" quite seriously, but it
had also been polished and ported so I wanted to use it.

To keep the cranking cylinder pressure to 160 lbs. (the maximum we have
found will tolerate 92 octane gas without detonation), I decided to use
two head gaskets - the modern, composition type. I used K & W Copper Coat
spray-on gasket sealer on both sides of each gasket. 

Over 26,000 hard-driven miles later, no leaks of any kinds.
