Hey guys,

I was preparing my collection of used heads yesterday to hot tank. I was removing all the stuff, like springs and valves, prior to hot tanking. I forgot to file the burr off ONEvalve (the burr caused by lotsa lifter banging) so naturally after whopping the stem to knock out the valve after removing keeper and spring, it cracked the cast iron guide part on top of the block. Is this a JB Weld repair, or a cast iron weld repair, or is it not readily repairable?

Never did it before since I always filed all the valve stems before! Rats, get interrupted by someone just for a minute and look what happened! Went ahead and hot tanked and await your advice on wheteer to junk or not.

Thanks,
rock

If you were gonna put new guides in it anyway it may be able to be repaired.

dont waste your time trying to JB weld something like that! Had a guy I knew with an Exploder, who had taken it in to a snake of a "mechanic" whose built a not so good reputation around here (the used car lots use him that want baling wire and chewing gum type corner cutting repairs on their stuff on the lot,) with what turned out to be a set of cracked heads, he told this guy I know that replacing the heads was unnecessary that a JB repair was just as good, and charged an outrageous price to do this along with what amounted to a head gasket replacement.... The guy fell for it, went and picked up the Exploder, drove it home fine, the very next day on the way to work the JB job failed and the "mechanic" could only shrug his shoulders and quote a head replacement job the 2nd time around, unwilling to even credit SOME of what the guy had paid only the day before! JB Weld has its place but not there!

I'm with Dennis here. If you are installing new guides, then it likely will not make any difference. If you don;t need new guides throughout, then just put a new one in that one valve guide. It should be a cheap fix.
