Kubota ZD221/D782 help

[346ci]

I bought a very low hour ZD221 with the D782 engine that had been overheated from not cleaning the radiator. The previous owner took it to a Kubota shop and they said it needed an engine.

I could tell they tried a new head gasket and replaced a bent push rod. I checked the head with a straight edge and could get a .003 feeler gauge under it. I let the local bike shop resurface the head, they took .008" off. He didn't have the ability to magnaflux for cracks so I had to skip that.

I know it not the best way to check but the rotating assembly feels good when turning by hand, bores look good.

My plan is to order a upper gasket kit and try what they did, with a flat cylinder head this time.

Good idea or wasting my time/money? I see reman engines for $4200 and from research, the D782 seems like a odd ball Kubota engine. I'm not willing to put that much in the mower, would sell it for parts as it has very low hours and in good shape.

My question is, do I need to add a shim to the head gasket to make up for the .008" that was taken off?

Thanks

Honestly I can't answer your question intelligently. I have heard that some people stack two head gaskets to lower compression on some engines. That trick would probably also make up your eight thou.

I kept the old gasket, going to try and pull it apart tonight to see which pieces are close to .008".

Thanks
