JD high comp head gasket

Tominwi · Jan 24, 2012

Where can a fella get a high compression head gasket for a unstyled JD A? I heard you have to use a all metal gasket, so I assume they meant copper? Thanks in advance

Is this just a pulling tractor? Id check with lubbock gaskets in lubbock texas. All copper gaskets will get hard after a short time and will leak water into the engine. I dont feel they are the way to go.

If a stock head gasket want hold,either your head or block isn't trew or your compression is higher than it needs to be.I have ran an A and G at 12.5 to 1 with no gasket problem.but they will not lug down when they are that high.the A was 245 lbs.A 730 deisel is 17 to 1 and uses no special gasket

For John Deere 2 cylinder pulling tractors I highly recommend TLH Enterprise,
Cedar MN. Guys name is Tim Harlin 763-350-0555. Tell him Kelly recommended him.

You are working with a engine that was designed to burn a low grade fuel. Raising the compression and not using a fuel to balance that will lead to gasket failure. Magneto couplers on those tractors had a 35 deg. advance. You will need to change that to around 25 deg.coupler so you will have some range on your timing. Unstyled "A" has spots in the head that flex & will eventually lead to gasket failure.They need to be reinforced. I personally don't care for copper gaskets. I usually "O" ring the block & head at slightly diff. dia. which gives it a lasting crimp on the stock metal faced gasket. "O" ring wire protrusion should be .005 - .006. If you can come up with better quality head studs it will make it a better job. Email me & I can walk you through it.
