Boring the block should do the trick nicely but as the head frooze I would have the block hot tanked and checked for cracks first before spending the money on machine shop work ... a good quality rebuild kit and you should be 100%

Still in the progress of getting everything scrubbed and cleaned. Then was thinking just die-penetrated to check for cracks. Has anybody had good luck just die-pen all parts? I' work on large marine engines on ships and die-penning is pretty standard for checking hairline cracks.The block and sleeves are cleaning up a lot nicer than it first appeared. We also have an older 36 A that gramps bought in late 60s for parts that is pretty complete as we'll. thinking of borrowing the head off it to get this one going first. The other 36A is in rougher shape but it's a nice machine with round spoke wheels with 10 spline still holding air. Both these tractors were used up to the late 60s and parked when gramps bought a pair of 4020s followed by 5020. Both 4020s are still are go to tractors where the 5020 was parked in a barn and is waiting for a turn in the shop now. I'll keep posting progress. Thanks everyone

You would be surprised how many tractors have welded heads. I would use the piece of metal and stainless rod like another poster suggested. You can grind off high spots where it will never show. Also if you need boring but not pistons have it sleeved like some others suggested. Normally "A" heads freeze crack but not blocks. Usually shops have them magnafluxed for cracks but the dye will work since you have access to it.

What I have seen done in a shop that repaired broken crankshafts for factory stamping presses (not engine crankshafts) they sprayed red dye on then a white dye. I don't really remember the sequence and I could have the colors reversed but they heated the area with a torch and the red dye showed the crack. Maybe they heated it first? They ground out the crack and welded the shaft and reground it. It's been years ago that I saw it done.
