I am putting 830 valves in a 730D head and I note that the part numbers for the springs are different. I have new 730D valve springs - the question is will I have to get new 830 valve springs instead? [Reply]   [No Email]

Might as well buy 830 springs. Let us know how your tractor performs with 830 valves. Someone asks on here from time to time but nobody (to my knowledge) has tried it and shared the results.

What is the seated and open spring pressures on the 730 & 830? Odds are the heavier 830 valves will require more pressure. [Reply]  [No Email]
