The 6 port secondaries will be closing at 70 degrees (stock porting). The
Racing Beat "J" bridge port closes at 72 degrees (mine close at 80) and the
Pport closes at 75 degrees. So the 6 port is quite hairy with no mods at all. So
in the street car they were closed until the engine got above 4,000 RPM. The
closing point of the primary (the one you ported already) will go unnoticed by
this engine. But the top end should be impressive.

I didn't
move the closing point at all on the side housings. I would
say that
they are still at 40° ABDC. I did move the closing in the
intermediate housing up, but I think they are almost exactly even with
the side housings. I'll check.
6,000RPM is my target for
cruising, so the stock is probably about
optimum.
