Isn't it amazing how fast a thread can deteriorate?Back in the day, my friends would suggesting going out to find some "crack", and I don't mean drugs either. It must have been something desirable at one time.

Read above...This may seem like a silly question to the veteran engine guys here but, it is plausible to think that a hairline crack in a head can be repaired? If so, any suggestions?
I had acquired a set of 'J' heads from a 340 (casting #3418915) from my local mechanic back in Canada for a small amount of money. I had them taken apart at another shop and put in the hot tank to clean them up. They were pronounced healthy but the engine builder in VA declined to use them because of the issue below:

Is it still 1.88 Intake? .I would 2.02 with a good hard seat ,let a GOOD MACHINIST ..with a three way cutter ,set the tone.
Is this worth trying to save or is it just a boat anchor now?
Why?Read above...
Because a bowl cutter ,just might remove the seat crack ,entire. Then you do a .003 -005 oversized hard seat ,for a safe interference fit. My cylinder headguy has used " Fluid weld " to stop all small leaks,under compression. Those,reverse taper pins , only goes so far ...Why?

Agreed, fix it correctly or throw it away.Honestly I'd get a different head. J head= who cares...
Good one j. I wouldn't and neither would you I bet.OR, I'd get it repaired good enough to pass on.....?
Yeah getting one over on somebody like that doesn't do it for me. I actually like this thread a lot more when we were talking about snowmobiles and quite honestly it was a lot more fun than talking about taking someone for a ride.Good one j. I wouldn't and neither would you I bet.
Hey wait a minute! Did I just make a funny? Snowmobiles? Taken for a ride? LOL
Do you really want to get me started on that crap LOL
Good thing no one mentioned Bars Leak.
why... not?lolDo you really want to get me started on that crap LOL
Repairs the crack through the spark plug hole?
Great! It sounds like they'll be for sale soon....LOLThe crack in the spark plug thread is no big deal.
It's not hard to install one seat. And it will fix it.
It works,In a pinch....Do you really want to get me started on that crap LOL
Then buy another casting Geez ...Great! It sounds like they'll be for sale soon....LOL
It works,In a pinch....
You want some of this !?Then buy another casting Geez ...
