Whats the revision on LS7 lifters? ok, so we all know LS7 lifters are the same that are in the LS1/2/4/6/7. except the lifters you buy now say "revised for LS7 high rpms" what exactly is changed on the lifters as opposed to the older versions?
does anyone have the spring rates at which the stock lifters start to fail?
personaly i see no need for any lifters besides these new LS7s, expecialy for the price ($125) but everyone always rants and raves about comps replacements, are they under 100 bucks or something?

When my lifter broke in my 05 C6 I bought LS7s which were the same part number as mine ?!?!?!? But, when I got them, GM went back to a fully enclosed lifter as opposed to the ones I had first which had 2 "perches" that the roller was attached to. Other then that the high RPM deal does sound like some pressure changes but I dunno.
