Building a 440 for my M715 project. Cleaned up the heads and will be bringing them to the machine shop but....want to get an opinion on what I found today. One head and a lot of rust on one cylinder. The other had a channel between the two center cylinders.
What do you think? Worth fixing?

I'm sure the pitting from the rust can be cleaned but what made the channel between the cylinders?

Blown head gasket would be my guess
 
HAVE IT PRESSURE TESTED. not alot of machine shops can do this, or will do this. I always have a cly. head pressure tested.
Cast or Aluminium.
 
Is it just an illusion or is the face of the head rolled in to the chamber a little in some spots? Looks like a sanding disc cut a little too deep along the edges. That could be bad.
 
Dropped the heads off at the machine shop last week. He said no problem on fixing the damage. Showed me his race heads that had a repair in the same spot. I weighed the heads. The 906 heads a 15 pounds lighter (each) than the 413 heads. Between the heads, intake, and waterpump, I'll be cutting over 100 pounds from the stock engine. Lots left to do but I'm getting excited for the big block M715 running through the deep water exhaust. Should sound pretty sweet compared to the stock straight six.
