Thanks for the product advice Norman, I went through the whole range of about a dozen gasket and silicone compounds but all of them said 'Not recommended for head gaskets' I will look for the one recommended, cheers.

Incidentally, does anybody know how hot the head gets? Some compounds are rated at 260 degrees Celsius, I am guessing that it would get much hotter than that.

Seems to be sealed fine without a gasket so far

For head gasket goo I use plain ol aluminum spray paint(cheap stuff and be sure its contents says aluminum) to coat the gasket for the head it can be used right away or wait until it dries. I have not tried no head gasket cause all my engines would let the piston smack the head with no head gasket.

Next go around I'm giving your paint trick a quick turn.....but the deal is I only have brush on Al paint. Don't want to rig the sprayer up for something so small.....can I lightly brush on a coat? (both sides of course)

The ancient can had gone off, so I bought a spray can - seems to be pretty high in aluminum flake....should last a LONG time!
