rodbolt, or anyone who can help me. i have a possible cracked head or warped, just pulled it off an hour ago. i see what appears to be fine cracks in combustion chambers 2 of 3 cylinders but not sure if they could be casting flaws. water jackets have a lot of corrosion also. is there a flush solution to clean these or can i use compressed air to blow them out without causing any more blockage. i should tell you the reason i pulled head in the first place was i had small amount of water in the # 3 sparkplug and had loss of power. i could pull sparkplug boot offf while running and it made no difference in power when i did on that cylinder. any input would be appreciated
