A friend is finishing up a 588 CID engine with B-1 original heads and KB aluminum block and needs a starting point for setting the ignition timing for the first day at the track (week or two).

The B-1 heads are milled to 63cc, so plenty of quench.
15 CR with flat top pistons, and 588 CID (4.5" bore x 4.625 stroke)
Roller cam, 279/293 at 0.050", 112 LSA, 110 ICL, 0.800"/0.760" with 1.7 rockers
Alcohol carb

What B-1 experience is there to share?
