318 head cleaning question

Update, this was awhile back for sure, before I had any clue what I was doing, and i still probably don't, but whatever lol. I think I ended up flushing the heads with diesel after letting them soak in degreaser, and shortly after removed one of the heads to check the cylinder walls and pistons on the drivers side of the block. All looked pretty good, I never oiled anything down so i'm hoping nothing has rusted while it sat, and if it has, that its not enough to require pulling the pistons to clean the walls (I have no idea how much surface rust on the walls calls for that). But i'm finally getting around to doing something with it, current plan is to rebuild the heads, replace dampener, make sure all is well with rotating assembly, and under the assumption that it is, i'll leave it together. New oil pan gasket and crank seal, timing chain, rear main, and the rest of the gaskets that it would need.
