I didn't do the work, so I don't have direct knowledge, but Bob Yarwood has
some challenges with leaks when he did my top end recently. Eventually it
was a matter of re-annealing the copper gasket, using a thin coat of "right
stuff" top and bottom, and following Mordy's instructions. Works fine.

Too early to tell for me -- I just got my 12:1 engine running yesterday and
I too have a Gasket Works copper gasket.  To seal it I made a mask to cover
the pistons and sprayed copper gasket sealant on the head, b oth sides of
the gasket, then masked the chambers and sprayed the head.
Let it set, then dropped the head onto the deck.  Let it sit for 10 minutes
with no nuts, then just finger snugged the head bolts.  Let that sit for
about six hours, then torqued to 20 pounds.  Did the finally torquing the
next day.  Hope it does not leak -- and that I have no reason to look for a
long time.

Hey all, I have a professional question to ask and maybe it'll be of some
help to others than myself.  I think I've discovered a cause of my
TR6 running hot. It seems to be a leak between the #6 cylinder and the water
jacket at the head gasket.  I say this because I can seen the gasket is
darker in that area.  Now the question, I have a copper head gasket and have
been told many ways to make it seal, but I want to get the opinion of the
people who make and install these gaskets.  It is a very good quality gasket
made by Gasket Works and I don't see any other damage to it.  Before
assembling the motor, I had the block decked .020"
and the head was check for trueness.  I'm pretty sure those 2 items are
flat.  I really would like to use the copper gasket if possible but could go
to a composition gasket if the reasons are there.  What do you all think?
