I had the same problem with Casper 1957 TR3. I finally found a 
mechanic who did some serious checking and discovered my 87mm liners 
were too short, therefore not sealing correctly with any sort of head 
gasket.  Once they were replaced all is well.  It is a theory you 
might want to check out ...

>A well trusted source has suggested that the new gaskets are built

>He suggested a solid copper gasket, which he uses in his tr3/tr4 
>racing engines and suggest they may be the answer.
>I have been on Gasket Works web site, and it seems to make sense. 
>They also discuss at length the o-rings required.
>What are the list's opinions on solid copper head gaskets? .. also
