Its been a while since I done mine, but I am sure that the valves in the vertical Starting engines are the same , 5B.5101 intake, 4B.7264 exhaust, Ken
The valve are the same used for the pony motors on the D7 or D8. When I did mine I got some from Cat, but they only had either the intake or exhast. I don't remember. I found that the Allis Challmers WD30 were a match and got them thru a local head shop. Also had to use the keepers. Worked out fine. Hope tis helps. [email protected]
Cat still makes the exhaust valves for a ten. Just need to know the current part number which is 4b7264
