Magnum Heads

Dave, Thats cheap for those heads and yes the heads are the same as the 318s. The cracks are visiable on most but the middle cylinders have to be magnafluxed. The end cylinders are the ones that crack the easiest as the coolant flow isn't as good there. Yes the heads have to be repaired as the water jackets are very close to the seats, what we do is interlock the seats so this doesn't happen again, then recut the valve seats.
I'll have to check on the casting #s for you next week as the only time that I can get with the engineers is on mondays when they'er not teaching classes,(techs) on new car services. Then if they'er not in Detroit or somewhere else. The only 2 guy's that I talk to is Chris and Ed.
