I am pretty sure I have removed all the nut and bolts that keep the head attatched to the block, and yet the head will not come free. Does the seal ever hold on th head so well that it won"t even budge? I have a feeling that I missed something really obvious and I just can"t see anything.

I removed the rocker arms by taking off the nuts.
The head bolts were secured with nuts that came off fairly easily. My concern here is that the bolts that the nuts were on stayed in the head. Is this normal? Or should they come out?

Other than that I have been tapping on the head to try and free it up , but it seems very "stuck"...no give whatsoever. Any ideas would be greatly appreciated.

Just pulled the head on A this weekend. The head did not want to move unitl I took the handle of my breaker bar and stuck in a couple of the exhaust ports and rocked it couple times. No hammers needed, just fairly firm pressure up/down. It broke loose after a couple of tugs.

Had same problem with my Super A. The main culprit appeared to be the crud around the (long) studs, which indeed remain in the engine block. So soaking the studs with penetrating oil real good helps. I loosely screwed a bolt into every threaded hole in the head. Then placed a 2 by 6 over and across the engine. Then took some twine and looped this from one bolt, OVER the 2 by 6, to the next bolt. Then OVER the 2 by 6 again to bolt number three. Using all bolts and other "protruding things" like the rock shaft, coolant inlet, etc. I weaved a whole cob web. The 2 by 6 was supported on one end and I lifted the other end with a jack, putting the cob web under tension. While hitting the head with a wooden mallet, the head finally came loose, undamaged! Clear as mud? Too bad I didn't take a picture :-(

Take a rigid paint scraper and tap it carefully between the head and block, without gouging either one. It will come loose. The studs will not come out unless you unscrew them.

Tip from the N board. Leave two bolts, one on each end, fairly loose. Remove the spark plugs and cram as much SOFT cotton rope down in the cylinders as you can. Then slowly turn the engine over by hand. If necessary put a socket on the crankshaft nut for more leverage. Seems to work right good.

No crank shaft nut. I hit mine with a RUBBER dead blow hammer, just needs to be popped loose.

I have tried the dead blow hammer routine and it just won't give.

The idea about the cotton rope sounds interesting, but doesn't that mean I have to take the engine off the tractor first? I hope to do that eventually, but I was under the impression that I need to get the head off first??? If not, how do folks pull the engine with the head on?Where is a good place to hook up to the engine?

I could probably make something work, but what have other folks done to make it easier and safe?

There are several threaded holes to hook a chain to remove the engine. You can also hook to the headbolts that stick thru the head. I use a nylon strap going around the whole engine when pulling one and transfering to the engine stand as you will want the clutch mounted to the stand. Use a 5# deadblow hammer or a strong putty knife in the gasket as there are two pieces of metal used in the head gasket drive between them in the soft center. Sometimes the head is pretty tight.
