I have a fresh street wedge block with pistons matched. The pistons were originally high ratio Maxwedge but had the domes cut to low ratio height with the plans to run as a stocker back in the early 90’s. Been bagged ever since.

.030”, bored and honed with plates, parallel decked for clean up only, fresh cam bearings, was baked and blasted.
Has the A stamp on the pad - 1965.

Won’t separate the pistons.
