How can I tell the difference between hydraulic and solid lifters for my '65 big twin?

OK, great. Thanks. I have changed them in my EVO, and r&r'd the Jim's Powerlifts in my Shovel, but when I removed the units in the Pan, they just looked wierd. The tappet roller assembly is like the hydraulic unit, but all that is in them is a spring, and a different, one piece lifter assembly. I guess that is one form of a "solid"? Isn't the expansion of the lifter limited some how, to so many thousanths of an inch, in the hydraulic unit? I am getting oversized hydraulics to convert it back to a stock configuration, after getting the gude blocks properly honed.

You might post a pic, but sounds like a conversion kit to solids. Look anything like these?

Yup, just like the picture of the whole setup on the bottom, with the adjustable aluminum rods. Now I know. That is the kind of info that I look for on this forum, rather than the battles that seem to form on some of the others. Heck, I might actually make a donation!
