Picked up a "was running when pulled" magnum 360 for $100 a while back. Heads, intake and oil pan were taken off. Short block looks good. I soaked the combustion chamber down with wd40, heated them up found a crack in one of the heads, other head looked ok. Last night i took the plate off the bottom of the intake. Here are a few photos of what i found. I know this is a common problem with the heads and intake. Just thought id throw it out there.
