Generally speaking, it depends on the pump model, not the tractor it's on. I don't recall ever working on an IH 856, but I have worked on injection pumps on many tractors, e.g. Simms, CAV, Diesel Kiki, Roosamaster(Stanadyne), American Bosch, etc. Going back maybe to the mid-late 70s, when tractor pulling was not such a big business affair, I used to go to the county fair every year and help out some of the local farmers/customers - by turning up their pumps for them. They'd have fun, pull and make smoke, and when the pulls were over I'd turn the pumps back down back down. Back then the pulling sleds were home-made which I kind of miss. Most of the tractors were John Deeres, ACs, and IHs - but I don't remember which models of IHs. If you've got a RoosaMaster distributor pumps like a DB, or DB2, the only catch to turning it up is if the pump has limiting shims. At one time, the Deere 4010s also had them. When the pumps left the factory, new, there were shims behind the leaf spring (that determines fuel delivery) that would stop you from turning it up very much. Most pumps that get rebuilt (that I've seen or know of), wind up with the shims tossed in the garbage. So, if you reach in the pump with and allen wrench, and the leaf spring screw only turns a 1/4 turn and stops, that's probably why.
