Magnum Adventure

Considering most of the engines I pulled the heads off had been in the yard less than a month (worked at this junkyard), doubtful. I didn't say either that no other engine suffers this issue. I was just staring at a pair of 4.6 heads at the machine shop that cracked in between the valves. I never said every set of Magnum heads cracks or any such thing. I just said, I have seen it happen. Sorry if it came off like I was trashing Magnum heads. I was just saying perhaps they have cracked. Jeez.
