Seriously... who is actually making parts in the U.S. any longer or in the last how many years for that matter?
Correct mostly made in China, but the ones from dealeerships had quality control. It will be your decision in the end. The owner where I did the last one thought I was wrong until the bill kept growing and growing, but we finished it. It costed $40000 more than he thought because of all the problems.
The dozer was only worth $25000. Motor costed around $95000 with all the screwing around.

Is this also rubbish?

All I can tell you is that if you zoom in on the picture to 300% you will see that it is a KMP Brand gasket kit. Same company I built a few Komatsu's from.
Imagine the head bolt holes in the gasket being out 1/8 inch and having to die grind to fit bolts through head into block.
I did an international engine head gasket and oil hole was in wrong place.
There valve cover gaskets were I thought pretty good.
Lets not even talk about water pump parts. No quqlity control at all.
Thrust washers on crank were Zero clearance so found good used set.
There is zero customer support and so many wasted days.
Oil pan gaskets were always made wrong on 2 different model engine.
If someone thinks otherwise, jump into it, I would not stop anyone.
