SUCCESS!!
My pal Dickopedia, my son and I removed the engine in 3 Hrs not ever having done it before so we were really careful thanks to my friend Dick.
I took lots of pics so we could re install the wiring and fuel lines etc.
Couldnt believe how easy it was except the bearing from the brg support kit took a little finegeling to remove but came off OK .
Got it done at about 3;30PM.
Put a lot of the old fashioned permatex form a gasket on the pan , gasket and block.
Super glad I put a 1100 pound hoist on a beam in my shop last winter.
Wont put oil in until Monday AM to be sure that the permarex cures.

It initially looked like more than we wanted to tackle but once started was a cinch.

Thanks to Marty and this thread, I decided to replace my head gasket as a preventative measure. My 51hp perkapillar wasn't showing any signs, whatsoever, of it being blown. Well......it WAS blown in between two cylinders! Sure glad I decided to do it, otherwise it may have been a piece of scrap metal in the near future. My engine is a 2006, and has 3,300hrs on it. Maintenance has been done religiously, oil changes, air filter, fuel filter every 100hrs. About 6 months back, I popped the oil fill cap to see if I noticed any carbon deposits. At the time I saw none partly because the deposit was at the far end of the valve cover where I couldn't see.
  My recommendation to anyone with this engine with the old style head gasket is this... Just replace it, and save yourself buying a new engine. 90% chance it's blown based on my hillbilly statistical analyses.

Anyone ever find out if you can drop the oil pan without removing the engine?

Hello,
   You will need to raise the engine to remove the oil pan. It is not a big job "  No Fear" lifting the engine will be the biggest challenge.

I hope this helps. Like you said if there are no signs of the gasket being blown when it fails it damages the engine most times it is not repairable .

The oil pickup tube and screen hangs well down in the pan about 2/3 of the way toward the fan end,

(see the very poor pic) but I doubt you can do it without either removing the engine as we did or just raising it as Marty suggests, plus we didnt trust my hoist completely so removed it and put saw horses under the engine in addition to the hoist.
We decided to remove it as werent sure there was enough slack in the various wires to get the engine high enough to work on.
Another thing, the cat manual that came with the mill indicates 10.3 qts of oil, but this way overfilled the engine.
I use 8qts.

Well thanks for the feedback guys, I cranked it up today(haven't dropped the pan yet) just to make sure everything was working right, with no leaks.
  Pete, yup, I've discovered the 8 quarts to fill as well. The fluid capacity in the WM manual is just a few quarts off haha.
  Marty you mention most times the engine can't be repaired....do you mean scored pistons or warped head? I checked my cylinder head per the service manual with the feeler gauge and straight edge, and everything checked out. The cylinder bores still had the cross hatching too. One thing I did notice, is that the engine pops off quicker on start up, so I definitely think that bad gasket was robbing me of compression.
  So on the pickup tube, am I basically just looking to make sure it's not all clogged up with carbon? Did you guys pull it, brake clean it, and reinstall? Thanks.

Hello,
  There are two different oil pans. The 62 hp is 11 qt and the 51 hp is 8 qt.

Does the head gasket for the 51 hp Cat come as a set or by itself? Any one have the part number handy for the gasket? My WM with the 51 hp Cat is a 2005 model.

Thanks,

Hello, 
    I have never purchased a Gasket Set. It always comes as one head gasket. The other gaskets or o - rings can be reused.
