Changing heads/Cleaning

[akart]

I am putting on some new heads w/the engine in the truck. I want to clean the piston tops/decarbon. I am seeing WD40 and scotch bright pads and also the use of oven cleaner. Well: It seems like the scotch bright pads would get abrasives down in the engine and bearings (me thinks not good) and the oven cleaner can disolve aluminum and that doesn't sound good either. So.any suggestions? I was thinking of running Sea Foam through the engine before tear down and a bronze brush and/or some plastic or wood scrapers w/some WD40 and maybe Sea Foam as a solvent too.
