A closed set pressure of 140 lbs would "only" work for a hydraulic roller cam with the lift in the low .500s, not a solid roller (SR) with the lift at the valve in the 600+ range.
With my SR cams for SBCs, I've been using PAC-1243 springs. Which install at 1.900, w/ 240 closed seat pressure, 625 open and coil-bind at 1.100. That in-turn allows for .700 lift at the valve without any problems.
The .100" longer valves should work to achieve the 1.900" installed height, which is typical for the SR cam valve springs. And, I would not settle for anything less-than the 1.900 installed height.
