I had to hook it up to an engine hoist, had the tractor front off the ground and still wouldn"t come loose, ended up using a rose bud playing along the top of the head and when it got nice and warm it popped loose. Turned it was put on with permatex. HTH"s. Lee [Reply]  [No Email]

Dad took all the head bolts out and the heads would not come off..I guess they had been "Permatexed".. He drove it up and down the road with the head bolts all loose and they never did come off.. Scrapped that engine... "I am not a fan of Permatex"..!!! Ron.. [Reply]  [No Email]

Stick a pry bar into one of the exhaust ports in the head and lift. I usually use my 1/2" drive breaker bar. If that doesn't work, put the spark plugs back in and then bump the starter. Forget filling the cylinders with oil. The compression alone should do the trick. [Reply]  [No Email]

You don't have to use the head bolts, but put some in that are of similar length, leave about 1/4" loose. That way when the head pups off, it doesn't slide to the side, and land on the floor!

Wouldn't it be better to spin her with the hand crank to keep the spin slow if you did this? Just curious. I figure the issue is that the old head gasket has become like a super bond between the head and the block. I had the same problem taking an old carb off my WD. Basically had to use a block of wood so I could hit the top side with a hammer to knock the carb off -- and it was just a small, old paper gasket that had fused the two pieces of metal together.

It can take some real brute force to pop them loose. I wonder if you could pull the #1 or 4 plug and chuck up an air compressor and see if that'd pop one end loose. AaronSEIA [Reply]  [No Email]

Now if you had said fill the cylinders with a small diameter rope that will also work [Reply]  [No Email]

Fill the cylinders with oil put the plugs back in and then use the starter to spin it over. The head then has to move due to the hyd effect [Reply]  [No Email]

Feed a piece of rope in thru a spark plug hole and let it pile up on top the piston. Then roll it over until the piston pushes the rope against the head. Way better than a liquid! [Reply]  [No Email]
