Putting the foot of the lifter against the side of another lifter will show if the foot's convex. Or use a straight edge like the side of a machinist rule.

Pat close attention to any lifter from a lobe that shows anything out of the ordinary.

Rocker studs

Running a sbc with heaver spings can run into probblems with the press in rocker studs pulling up and changing your clearnces. A cheap fix for this has bin drilling a small hole in the side of each boss and running a small roll pin threw them to hold them. I think the best fix is to pull the heads and remove the press in style and machine the bosses down and tap so screw in studs would then be used fixing the problem for good. YOu cam looks like normal wear from all the photos. I would pull a valve caver and check to see if you studs are still the press in style and if the are see if the are ann the same hight. this can tell if they are starting to pull out.

I had a SBC with screw in studs and used blue lock tight. They actually would loosen up enough to bend a push rod. I ended up pinning them like the last post said and my problems went away.
