Marv,
I too would be very interested in a thick head gasket. The head on my TR3B
has been milled too skinny and the result is a hot running motor. I also
have had a problem adjusting the valves for years. There are aluminum
spacers under the rocker shaft pedals and I will adjust the valves only to
find they are out again a day later. The valves are also very loud which is
annoying to me.
Never understood why an engine rebuilder will shave head as a matter of
course whether they need it or not. You simply cannot easily buy high enough
octane gas to make them run smoothly with a high compression ratio. I say
the cars were fast enough in stock form. Now if it is a race car that's a
different story. Do you want the motor to last a couple of years or like two
races?
I have been told that you can use two regular head gaskets. Has anyone tried
that?
