Head ID and Correct Plug Please

Small block heads # 333882. What do these go to and what is the right AC plug for them? Thanks as always.

The GM casting #333882 heads were used for a wide array of Chevrolet small block applications in the mid to late 70s. For Corvettes, they were used on 1974 through 1977 year models. These heads are of approximately 76 cc combustion chamber volume and were produced in both 1.94/1.50" and 2.02/1.60" valve size.

All 333882 castings are machined for taper seat ("peanut") spark plugs. The AC R-44T (GM #5613355) and AC R-44TS (GM #5613303) were some of the commonly used ones for Corvettes.
