They are available standard journal. My father is running a Lunati 4-7 swap in his.

But my comment was more related to BBC, SBC that the test was done on because those engines also have the LS firing order cam core available as well as the 4 pattern camshaft available, both of which aren't available for Pontiac that I'm aware of, and since the test was done on a BBC anyway, it had me curious. Just seems to me that would make a significant difference in header choices.
