I'm asking for some input i have a 94 gmc 2500 6.5 turbo was leaking coolant so tore the heads off to find that driver side head blew the head gasket. I cleaned the heads to take them to get resurfaced found cracks between the vavles should i clean them up more and run them.btw the casting numbers on the head is 10137567
Thanks rusty

 

You might be able to make it work but personally I'd just swap them for a new (I'm sure someone will chime in with a good upgrade or aftermarket I haven't really looked into a head upgrade yet) or GOOD used set it sounds like more headaches ahead, if you already have stress cracks the metal is already weakened. I'd rather put it back with parts I could trust. Just my two cents

 

Not to mention it could end in much more pricey damage depending on how they fail spending a dollar to save a nickel as it were

 

Yea i thought money spent on gaskets bolts just to put it back together and a chance that they would be junk
Thanks Rusty

 

Don't scrap them brass liner tubing can be installed and coolant won't leak through they'll be better than new search on youtube 6.5 cracked head fix
