Still...regarding the head gasket, the water only comes in contact with
the edges of the coolant as it surges through the passage ways. Speaking
of which: On the Gasket works site they imply they can make their
gaskets so that one gets more water circulation at the back of the head.
I also mentioned they made gaskets for marine engines. I'm guessing the
addition of salt in the mix would not be a good thing - unless they do
so for only fresh water craft.
One last positive: Should one be considering installing a turbo or
supercharger, GW could make a very thick head gasket to bring down the
compression. Might not be as good as replacing the pistons with lower
compression ones (I assume custom machined forged pistons) but sure
would save a lot of time and energy.
Hmmm.. I vagely remember a thick metal head gasket as part of the Jafco
turbo kit.. as described to me by one of
