Dam when you lay it out the numbers dont lie dual pattern would win the race.
I am still waiting to here back from Racer Brown, their shop got flooded, not real bad but Jim said they have a lot of clean up to do.
That’s the problem using numbers. You can’t ignore overlap and think it doesn’t matter. A good header and correct cam timing with a single pattern cam will beat up on a split pattern cam every time. When things like the LSA get opened up for idle quality and such the engine gets less responsive to exhaust changes, because you defeat overlap.
