Luke, the second type was called the "barbell" type, as you can see from the profile. The lifter Brent may have may be a full body outer shell, but with a fixed plunger inside, with the pushrod seat near the top. A solid steel lifter I think would be very heavy, so to make the solid lifter 2 piece would cut down on the weight, with havin a cavity inside the lifter. I would think tightening the valve lash until either the pushrod moves or the valve moves will determine what type of lifter, other than taking out the lifter itself and inspecting it.

I don't know if you can use the barbell type in a hydraulic lifter block, but I think you can use the shell type, and probably a full body solid lifter like what brent may have.
