well i did cut the screw head off.. i only had about 1/4 in of threads... the beveled head of the screw fit perfect in the top of the spring..but i still had to grind the top of the head down all the way until there were no slot left...
when i finally got 74 psi it measured 26 thousandths " FROM THE TOP OFTHE SPRING TO THE TOP OF THE SCREW HEAD" thats with the spring standing up on one end...
i wisg i knew how to do pictures on here so i could show you
if you dont understand how i measured let me know and i "ll try to explain it a better WAY
"FLATHEADS" all other fish are just bait

Here's what I've been wondering.... what do you do to "lock in" the final screw position? In my inexperienced mindset, I cna imaging engine vibration causing a little "self-adjustment" over time, ending up changing the fuel pressure you're getting.

when the screw threads into the spring , it fits pretty snug, i dont feel like it will move..also the screw on mine is threaded all the way in until the beveled edge of the srew bottoms out against the spring...its pretty tough to remove the screw , u have to hold the spring with needle nose and turn the screw...its pretty tight...
i did not measure how long the threads were when i finished but im going to guess about 150 thousandths.. which is a little over an 1/8 of and inch for sure no longer than a 1/4 of an inch. -----------}}} (//]
hope this helps
