Only about a hour, that's surprising!
These 16 heads took a 455 in a early Bird that was 3450 with driver into the low 10.20s I had custom 2.14" valves made up so I could run 45 degree seats and not sink the valve, also by doing that was able to get most of the upper part of the valve bowl quite big as you can see in the one photo. This allowed me to get a stout 155 cfm@ .200" lift which really helped the VE numbers.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
