Suppose one has a head gasket failure(composite gasket) on an engine with a cast iron block/head. The cause of the failure has been determined, and the engine will remain in the car and assembled while the a machine shop does a light skim on the head(6 thou) to correct a small amount of warp.
Left behind on the deck of the block is some gasket residue and also some firing residue from the breached gasket. I'm guessing a plastic scraper is in order(after removing the head studs for complete access). Are the gasket remover sprays available out there(I think Permatex and CRC among others make them) worth it, or can I get the same result with carb/brake cleaner, a plastic scraper, some shop towels, and elbow grease?
Obviously I'm trying to avoid having to redo this job again soon. I hadn't done a head gasket in a few years, and often times it's an asbestos/copper factory type gasket coming off that leaves little to no residue
