Hello John,  Your email did not come through. I hate putting address up on web cause it seems like I get all kinds of unwanted stuff when I do.  
 But here goes address-  <!-- e --><a href="mailto:butterflies@grantsburgtelcom.net">butterflies@grantsburgtelcom.net</a><!-- e -->  -this should have gotten you through at least into postine box at our internet provider here.  
 Phone number is 715 689 2433 .  
 Sometimes its hard to get hold of me and other times I am around.  Today, well yesterday I had to do some running around cause of a bladder tank sprung a leak and dumped water out of outdoor wood stove. Which in turn got seriously hot, (temp gauge at 280) so had to get that under control and limped the outfit through the night till I could get parts yesterday. then got it back together and baby sat it again to see if controls were functioning right. Heat has a wicked sense of humor with some controls. Pressure gauge shows 5# more and the temp is 8 degrees off. The aqua stats had to be readjusted too.
 Back to my '55, The engine has been apart now for several years in an old shed. I had put the head in a plastic bag but that plastic deteriorated. Turbo had been set up out of the way and I see the coons had to much fun by it and got knocked down. I had also layed plastic over the block and placed valve cover over it. Dirty birds turned stuff white.  At least the injector lines are still capped.
 I talked to my nephew about putting the tractor inside his shop where it could get warmed up and get started working and cleaning on it.  
I remember saying I bought it in like '79 but it could have been later, Specially if the numbers on the block 9184 were the month, day and year the block was casted. The seller said it was a fresh overhauled engine with the beefed up heavier block in it. And I took his word for that. 
 I plan on having the head pressure checked just in case it cracked, but I dont remember if I had heard a metal ping when it had let loose with antifreeze out the exhaust. You asked if I had the old head gasket yet, I think it was hard to get off and got torn, but I will look for it.
 Thanks for the words of encouragement with this tractor, Jerry
