Anybody make copper head gaskets for Kohler K181? I've got a feeling I'm going to be going through a lot of the stockers.

I believe Midwest or one of those folks sell them in different thicknesses.

I don't think that a copper head gasket is soft enough to use with an aluminum Kohler head. I've had trouble before with Kohler heads. They had warped alittle. I filed them flat again, used a new Kohler head gasket, chased all threads and torqued them according to the manual. One head I was not able to reuse because the head gasket leak caused a notch to be burned into the head. When I get my shaper set up, I will resurface the head. Good Luck, Rick

Any contact info for Midwest? The head I have is relatively flat. It's the block I'm worried about. Had it in the machine shop to replace a valve seat, and told them to lightly surface the deck to make sure it was flat. It looks like they drug it around the parking lot! I tried to polish it out with 140 grit on my sander, but it still has some deep scratches. I guess I'll try the stocker first, but one of the reasons I tore it down in the first place is the stock gasket failed on the deck side. Looked like a worm ate through it.

When I reuse a head gasket, I put aluminum paint on it.

The .031 copper gasket is $14.70. The .062 one is $21.00.

Thanks, Lilysdad. I was thinking of using some of the copper headgasket paste that they use on steel gaskets as well. The composite stock gasket really can't be reused successfully in my experience. Old steel sandwich Briggs gaskets on the other hand.... :D

I've done the same on the steel sandwich gaskets, and it's worked fine as long as the gasket isn't deeply scratched, etc.

I did some reading on the copper head gasket ideas. Almost everywhere you look, they say to anneal the gasket to make it more malleable.

My boat engine had copper head gaskets and I had to buy a can of a special sealer to use when I replaced a cracked block.. :wallbanging:   (I did a bad job of winterizing one year and paid dearly for it)  It still sits on the shelf in the shop & I look @ it every once in a while....   :(   That short block cost nearly 2K and that was back in 2006.. :anvil_drop:
