off with the head

Yep. Have seen hundreds of those. Probably going to need some guide work as well. Pay particular attention to the front end of the head to make sure machining for the seat insert does not hit the water jacket. Have seen a few heads with casting shift where that was the case. Also, be sure to get some later valves to go with the harder seats too.

yep hard seats are the fix for this problem , was planning on using my old valves but the machine shop may replace the valves also. not sure at this time, I will check and see what he has done, would love for this head job to last a long time, thanks for the heads up on the valves....Don

I just did this on my 4010 LP Deere tractor. It has hard seats from the factory so I didn't have to do that, but it still cost $750 to go through the head. All of my valves were junk as well. Once he had faced them they had lost 1/16" overall diameter!

I sure am glad that ole dollor is not a 4010 john deere ..that would hurt the pocket book, but it sure does make them run better.
