4 flats does not sound like enough but I've never used the FM's so I really don't know about those. I like the SE tapered rods because they are marked and it's two and a half rotations with them.

4 flats wouldn't even be 1 rotation...6 flats per rotation. I adjusted my Fuel Moto pushrods to 19 flats or 1 flat beyond 3 full rotations. It helps to have a way to mark the black flats - I used a small pick to etch an 'X' in the flat that was facing me to know when it had come back around.
It's still a little noisy so I'm going to check them again after I'm able to go for a ride which will be a few months here in Chicago.

I've adjusted small block V8's with solids or hydraulic lifters with the motors running, no problem. Concerning bleeding down the HD lifters. When I shut the motor down, a valve or two will be open. If I adjust the pushrods after the motor has cooled, the open valve will have bleed down the lifter before adjustment. I understand how to adjust the pumped up lifters and wait for them to bleed down before turning the motor to adjust the other pushrods, but what effect does the "bleed down" lifter (when motor was shut down) have on the procedure. It seems like that lifter would have no oil in it while the lifters on closed valves would be full of oil. How does this effect the adjustment procedure? After backing off the pushrod and then removing play, is the resistance the same with the pumped up (full of oil) lifter vs the bleed down unit?

First you have to know the tpi of your pushrods. If you are using Woods lifters he likes them set to .120 -.130" preload. If your rods are 24 tpi each turn equals .042 travel/turn, 32 tpi equals .031/turn. .125 preload /.031 = 4 turns. 6 flats on the nut x 4 turns= 24 flats. I like to count the flats as it is easier to keep track of and allows for .005/flat adjustment (32tpi). 23 flats = .120, 25 flats = .130
