Just got back from testing the springs. They were 190 seat/450 open using an on-car tester. I found the box the springs came in and they are the 68385x2 springs and retainers. These number appear to be spot on for that part. I think this should be enough pressure, but my machinist said he likes at least 240 on the seat for a solid roller and did recommend heavier springs. I'm really not sure where to go from here...
