did you remove the plunger from the rear of the block or from the oil pump?

The plunger and spring at the back of the block were removed.

The pressure relief assembly in the oil pump was left intact but modified.
The pressure relief spring in the oil pump was shimmed, thus a shorter spring travel to help insure a certain amount of relief but only at higher pressures, 100 psi and up.

The combination of these two mods insures a higher level of oil pressure throughout the RPM range.
