Valvetrain Geometry Facts Or A Bunch Of Bull Crap?

I have been trying to figure out how to check for push rod length. I have read all about it on here and other sights and don't know who to believe about how to do this or that. I called up summit racing tech today and i asked them about how to check for push rod length and they have never even heard of using a solid roller to check valve train geometry. Also i asked them about the wear mark on the valve tip. I have heard through research that you want the thinnest wear patter possible. Summit told me that that doesn't matter if the wear pattern is wide. So i don't know who to believe or what to do exactly.

Can anybody help me out and explain in good detail exactly how to check for push rod length and how to verify valve train geometry.

Hey thanks for the link. Some things that are not clear to me is when using a solid lifter for adjusting is do you have to add the preload that you normaly would have with a hyrdrolic to your pushrod length?

They d0nt use the method of using a solid roller. If i use a converted lifter do i need to add the preload amout that i would normally set to my overall pushrod length?

i will being using a half turn, do i need to add 0.028 to my push rod length?
