If youre just installing them then it doesnt matter. You just wanted the lifter all the way down on the lobe and make sure its not crooked

Sorry, but I am confused. Are you asking about lifter installation or rocker installation? The type of rocker won't influence how the lifters get installed.

Your heads may be milled too much but in general the t2 shouldnt have ptv issues

You never heard of using roller rockers instead of lifters? You get to really jack up the cam lift. when you multiply cam lift by 1.7 TWICE. That is probably why the PTV issues.

Technically you should, but plenty of people dont. How long are your pushrods? Also note most aftermarket cams have a smaller base circle so they require a longer than stock pushrod. Stock is 7.4 for reference.

ls7 lifters run about 0.50-.070 preload

given the preload (and im assuming stock unmilled heads) and smaller base circle you will probably end up needing 7.425 - 7.450

Yes stock unmilled.. really 7.4 should be right? I wonder where my mistake is I think I'm going to put each cylinder tdc and see if that works
