It's a 902

I dont think that can be repaired, or is worth repairing its 902 head.

Well, now you have a head with seven other ports you can practice your technique on, and one you can saw in half to see where the water is.

Yup.. Metal cutting Bandsaw Through a couple ports... Grind away, can't hurt it anymore than it already is.... Funny, I tend to be careful around the back side of the guide but I hog the throat a bunch...

It went through quick I didn't remove much material at all. I only had 2 more ports to go and I would have been done with both heads.

Will you flow the head after repair??

Steve Dullich published an article about porting Big Block Mopar heads... Amongst the pictures was this one of a sawed apart 906 which I find very informative.... Look at the back side of the guide... There's water on the short side too but not nearly so close....

Well I better finish my work before I get it repaired, just in case.

I looked at all the maps of heads I could find on other sites. Some were hand drawn and some were actual cut always. Like I said they are just 902 heads and I really haven't tried yet to find a replacement.
