And no slipped liners... hooray!
Speaking of RTV (Ruin That Vehicle) applications, I once saw a fan clutch and pulley that had been RTVed all the way around as a repair for weak clutch.
Here spec sheet on the "copper" RTV, widely available and rated for up to 600 F - and you will note that no where does it say for use on head gaskets. (And I am on the fence about exhaust gaskets - but maybe it is better than "muffler cement"). But being manly men, frequently we fail to RTMFB. In step # 5 of assembly instructions it is actually stated not to uses this on HG applications, either as a gasket or a dressing. Included this so others may see the errors of your previous owner.
Perhaps we should have a thread for Previous Owner Obnoxious Practices (POOP) with classes for "dumbest", "most costly", "sneaky", etc.

I got to work on cleaning up the carbon buildup last night. I was using some 00 steel wool and throttle body cleaner. Have to go by the autoparts store and get some gasket remover and a good scraper so i can get all the schmutz off. Any suggestions on something to really chew through the carbon so i'm not sitting there scrubbing for 3 hours?

Ahhh, all looks so familiar. Mine failed in exactly the same spot.
Have you been able to check for warpage on the heads yet? That would determine how much scrubbibg you will need to do. Obviously the machine shop will be cleaning them should they require decking.

Havent checked the heads yet, going to do that tonight. I'm just looking to clean the mating surfaces on the heads at the moment. If its out of spec then like you said i'll worry about letting the machine shop getting all the schmutz off the combustion chambers. If they are kosher as far as flatness goes then i'll scrub the chambers with the valves out. Going to lap the valves anyhow for good measure while i have it to bits.

Cleaned up the heads and checked with a feeler gauge, it's close so i'm going to err on the side of caution and have the heads decked. Better to spend the hundred bucks now rather than to cheap it out and have to do it all over again in 10k miles..

Something handy to include would be a list of everything you used to do the job and prices of anything you purchased. Would be highly informative to anyone attempting this job in the future.
