Yes ported.

The engine really seemed to like 18-20* of timing at idle. The distributor has ~15* of mech advance curve, and this puts it right where it needs to be as far as timing.

We may try it on FMV again but I'm afraid it will pull it out of the range it likes.
It seemed sensitive to much more timing at idle than 20*.

I've played with some combos that would barely idle at 20* (BBC with healthy solid roller) and liked 40-50 degrees at idle. However this one seems very happy at 18-20.
