Hi everybody, I would like to know if I can change the valve seats in the head of my WD and while i am here I would like to have the head resurfaced along with the top of the block. How much do you think I can remove from top of block without changing the compression ratio and not having trouble with piston hitting the valves? I know it is not a diesel engine and there is a big enough combustion chamber but I would like to know for sure. Oh and by the way It is a WD but it has a WD-45 crank along with cupped pistons Thank you very much in advance for all your opinions and reply. Have a nice day

Well, from 1957, that was all we pulled when plowing and in Central Ohio we have it ALL..Black-Jack and Jack Wax included..

Plowed many an acre of mature alfalfa..never fell below 2nd gear... 2 of us with 4 bottoms would leave a good mark in a field 1/2 mile long in a day..(60 acres) Dad'e came with his 45, a 4x14" semi-mounted.. Now, all tires were loaded to the top and a railroad rail chained in front of the radiator.. Dad's was one of the original "demonstrator tractors" and mine had a M&W kit in it..they were nearly a perfect match for power..

dont change the seats just cut them for bigger valves and while youre in the head change the valve guides from 3/8 to 11/32 helps flow bunches. relatively in expensive main cost is new 11/32 valves and retainers.

You can have the seats changed, if they need it and the head can be planed.. The cylinder block is a different story, as the sleeves set down into a recessed step at the top. Those machined steps must be cut the same amount as the deck surface.. I have heard of some cracking at the deck, so removing very much may only increase that tendency If you already have a '45 crank and mayby 4 1/8" pistons, you have a pretty stout tractor now.. I wouldn't want to ask a lot more out of it...! With enough weight, it can pull 4x14" plow now...! Ron.
