I have been using copper kote for almost 15 years now on MLS head gaskets. I have never had one leak coolant or oil.

Brake clean takes the stuff right off.

I would be hesitant to use anything silicone related on a head gasket, that stuff squishes out, gets in oil and water passages and hardens up. Prior to copper kote I was using hylomar, and now a permatex brush on non hardening sealant. But never rtv.the only spot it's good for is the oil pan corners, and China walls on the intake manifold.

We've been using the red RTV high temp silicone for 30 years without any problems.  Hard to switch products, sounds like your copper kote is good stuff

Niel,
I am like you, I have used red RTV on head gaskets for years, the trick is the coating of the RTV must be very thin, I usually run a very small line of the stuff around things that I think need to be sealed, i.e. water and oil passages, and then use my fingers to "rub" the RTV down to a very thin coating. Let is set for a few minutes and then assemble. With head gaskets we are only trying to fill the very small possible irregularities between two machined surfaces so the coating, copper plate or red RTV needs to be thin. To many people just gubber  on a big bead of RTV and then when at assembly it comes out the sides, down the water and oil passages and causes havoc. In this case the less you put on the better.

At Interscope we had many problems with exhaust header gaskets blowing out, both NA and turbo engines, we finally went to using just the high temp red RTV and never had a problem again. We did surface grind the header flanges so they were flat and true.

I put the block on an engine stand and cleaned the oil passages, main bearing bores, and cylinder liners with brushes and then sprayed them with brake cleaner. I also brushed & sprayed the lifter bores. I wiped the liners with lintless wipers after spraying them with brake cleaner and they are now as clean as I can get them. A light spray of WD-40 was the last step, just to prevent any rust. When the main bearing seals arrive (Monday or Tuesday) I will install them and the main bearings so that I can drop the crank in. I did a trial fit on the Milodon copper head gaskets and they look fine. It was not easy getting them out of the skin pack without bending them. They are really SOFT!
