1971-era Pontiac big-valve D-port
Valves: 2.11" intake / 1.77" exhaust
Screw-in rocker studs: commonly referenced as 7/16"
Nominal chamber: commonly listed around 96 cc
The larger chamber works particularly well with a 455 because it gives you a much more street-friendly compression ratio than the earlier 72-75 cc performance heads.
These heads are in excellent working order, had new valves about 5000 miles ago, mild porting, and came off my 1971 GTO 455. I replaced them with KRE Aluminum heads.
