Brent: A quick way to determine whether or not the lifters in your engine are solid or hydraulic is to pull a valve cover, then find a rocker arm whose valve is on its seat. In other words, there's a little lash at the rocker arm. Now, push the rocker arm so it's lighly against the pushrod, then push the rocker arm hard to see if there's any additional movement. If it's a hydraulic lifter there will be a slight amount of movement as you push the lifter plunger into the lifter body. If there's no movement no matter how hard you push, you've got solid lifters.
By the way, the term "solid" used in this context doesn't mean the lifter is one solid chunk, but it's hollow and the pushrod cup is fixed solid in the lifter body rather than sittting on top of a compressible plunger as with the hydraulic setup.
Hope that's a hint that works for you.
