MATT,
removed the heads and on the exhaust side on the flat side of the head is a very dark almost black, 1/2 to 3/4 inch around the valve that almost looks burn. is this  very lean or normal the flames are a very pretty blue at night. also this is a dry block and heads

second is there a way to see if there is a crack in the  2 oil galleys in the block.

as always thanks for your time
