Am I Going To Be Happy With This Camshaft?

I get it with the headers. I always understood the asymmetrical profiles were for factory manifold cars. I can real back my order but I think we are splitting hairs at this point.
You would be correct. There's nothing written in stone that says a split pattern is best for manifolds and single pattern best for headers. That's an unknown that cannot be known until you hit the street, drag strip or dyno. And yes, it's splittin hairs. I wouldn't sweat it a bit.
