Sorry about that Russ, I had forgotten about the wrong spring specs until you mentioned it,, the cam card is wrong that came with my cam,,, on the web site for my Hydro cam it says 155 seat 415 open, when I got the cam I had to call & sort out what springs are correct & they said it was a missprint for the 220 seat springs, as Dwayne said I have Beehives, also I totally agree on my .020 from the bottom is really just a lash setting. here is the cam card from the website The lifters are .120 travel, I got longer pushrods so I could set them from the bottom of travel & keep the amount of threads on the adjusters correct,, Needless to say but, the only way a pushrod can fall out on my junker is if something REALLY breaks & fails, not just a collapsed hydro lifter
