Valve guide clearance

OK, I got the valves to slide in after carefully measuring the valve stems and using the smallest in the tightest guide and so on. I had 4 .315 (8mm) valves, and they measured .3161,2,3 and 4 using a .0001 micrometer and its 'clutch' end. (If these are accurate or not, they are all measured the same way so at least the variances are noted) and I was able to find an order of installation that allows all of them to slide in to their guides with just a tad of interference but all are light fingertip push and pull capable, especially at the operating zone of lift. Im not sure what .001 clearance feels like but these fit so well that they draw a considerable amount of vacuum and pressure when I plug the guide hole end with my finger. My adjustable reamer shows up on monday and I dont know if I even need it anymore. Do bronze guides with their lube type metallurgy even allow the steel stems to possibly hang against a 50lb (?) closed dual spring?
