Here is a common lifter sold by PBM, made by Morel these are very good lifters for the money. Seems to be the same lifter offered by Lunati, Herbert and other company's etc. I took a bunch of measurements on these also and posted them several months back.
The wont clear the taller lifter boss's in the aftermarket block's however. I can get these for well under $300 a set, and they have been proven reliable.
