I looked around, not much about this on here. Nothing! I'm cleaning up my cylinder heads, lots of crap/corrosion at the edges near the valley and on the exhaust side. My cylinder head guy cleaned up the exhaust port area a little bit with ... something or other. Seemed like more corrosion the further back you got on where the header mounts. Mostly I need to know about the head gasket sealing area, is anyone using surface conditioning pads? This is against practice but maybe there is a silver bullet solution. I've gone over it about 3x with gasket remover, seems fairly smooth but there are a lot of rough areas outside of where the original gasket sat.
