Cracked head

Well I removed the head and found a crack running from one of the center holes over to the second cylinder from the front, where the water was linking out of the exhaust port. I assume this is also what is causing the radiator overflow? Ckecked thermostat again and the pointy end is toward the radiator.
I have taken this head off so many times that I think it best to purchase a new one. What do you all think? Any suggestions on where to purchase and type?
Thanks again for all your help.

Hey No way it’s the head it gotta be leak’in from the head bolts, yer gotta put sealer on’em, you have been told that up’teen times but not from me. Been their and done the head R&R a few times and kick myself cuzz I should’a seen the crack, it s so simple ain’t it. Its time fer a nice new shinn’e one, don’t need enny one ell’izz problems. Git a new one and don’t look back.

HOBO, I have always used sealent on the head bolts. They were all dry. Are you saying I need to pull the head studs? (Hope not)
I was hopeful that the crack was the only problem. Are you suggesting the water can only be coming from a bolt/stud? I have a new head on order...
Thanks for your help

Seems every time sumone has a problem like yours the anwser izz to put thread sealer on the bolt threads. I have ask For them to explain why water would chose to leak into a cylinder at the head bolt if no sealer izz used when it has 18 to 20 other holes that do dot have a bolt to clamp the gasket tight around it and I git no answer so why would this be recommended to stop water from git’in into the cylinder. Its simple it ain’t yer problem I felt all along it wuz the head. Yes put sealer on the bolts this will help keep water from leak’in by the bolt/stud to the out side of the head but not much help to the inside. I have also been bit by a cracked head just in to big a hurry to Git-R-Done

Wengers is good for hard to find parts.. but they are priced like they are a gov't contractor.

A new head from the parts section on this site is:
Cylinder Head - For 2N, 8N, 9N all GAS 1939-52. Cylinder Head (Part No: 8N6050A) $138.52

A used head from john smith is:
Good used cylinder head for 9-2-8N tractor with front distributor. $60 - plus shipping Good used cylinder head for 8N tractor with side distributor. $75 - plus shipping

Your choice.. used w/ some life left and good.. cheap.. or shiny new, and twice the price of the used one from the smith.. and only 10 bucks more than the used one from wengers.

I've bought parts both from this board and john smith.. can't go wrong either way.

I certainly sounds like you found your problem.

Clean up the deck surface, and take a GOOD look for cracks there, before replacing the head.
