Greetings, new to the forum.
I have a cracked head on my M4070 tractor and need a replacement. I see many different manufacturers with replacement heads available. Has anyone ordered a aftermarket head and have it not crack again?
are the head bolts torque to yield and do they need to be replaced?

Just to ad to the post,
it looks like kubota discontinued this head so no factory heads available.

Kumar brothers is the one that I have seen good reports on. They may sell complete and incomplete versions of heads so be careful about comparing the costs.

The head cracked from over heating.
So look at the cooling system completely.
The head bolts are reusable.
Get an OEM head gasket if available.

I looked-up a M4070 on TractorData and it’s not listed. What year, etc. is it?

I wonder how many V3307 heads I threw away? Along with mandatorily-damaged blocks and complete engines? Plenty of them. Had one at the house for years and nobody wanted it. I had it in my fox body mustang for a bit (never drove it) just for giggles. It actually fits. I wanted to but the 427 got done before I got to figuring out the trans and everything else so out it came, sat in the corner for, gosh, 5 years or so, was on marketplace for $200, and it just sat there. Went to scrap along with a bunch of other stuff.

Always happens like that, no one needs one till they do. Ordered a complete head from amazon, its coming on a slow boat from China from what I can see.
