Cleaning 50k mile shortblock after removing heads in prep for Cometic & ETPs
Well, I just picked up my 2002 LS1 pullout that will be used for my Rx-7. I will be pulling the heads off tomorrow. I know that it is very important to have the deck very clean to ensure that the new heads seal properly. I know this is even more important when using a Cometic v. a GM MLS gasket since the Cometics are more prone to leaking if not installed properly. All that said, what is the best thing to use to clean the deck once I remove the heads?

I used a razor blade on mine but a lot of people aren't comfortable with that b/c it can gouge the aluminum block/heads. If you want to play it safe, use a plastic ice scraper to get the gasket crap off of both surfaces and then some brake cleaner with a rag to clean up whatever is left behind. Or, if you have a dremel, hook up a wire brush to the end and lightly go over the surfaces.

I used a razor blade when my plastic scraper wouldn't cut the mustard. I also follwed it around with a shopvac while I was scraping to keep **** out of the water jacket/bolt holes. Afterwards I made a thread chaser and blew all the **** out of the bolt holes using a small hose and my air compressor.

Use gasket remover and cloth. No sharp objects.
As you mentionned surface needs to be smooth. Als spray the gaskets with a light coat of copper sealant and you'll be good to go.

After masking off the bores and lifter area's so no foreign particles could enter the internals I used a wire brush on my dremel to lightly hit the deck. Works wonders as long as you are good and don't go crazy. B12 Chemtool is strong stuff and should work well with the plastic putty scraper if you don't want to use a dremel tool.

I just dis-assembled my 02 and it took all of five minutes to clean each side. I sprayed some gasket remover on there, waited a few minutes, then wiped it clean with a rag. (Don't get the gasket remover on anything plastic or any painted surface.)
Don't forget to suck the coolant from the heads before cracking them open. This will also hasten the clean-up.
PS I also noticed that the gasket remover is a good solvent for carbon on the piston tops.
