Can I use B or C body manifolds fore better flow on my sleeper GTS?

I smell what your stepping in
The manifold is attractive because of the obvious reasons, budget being one.

If we were to have a stock stroke (gasp) 440 at +.04 with 10.5 comp and a .245 @ .05 / 108 sep cam and a good head (stealth) or better.
what is the "loss" of the manifold..?


Niiiiiiiitrooooooooooooouuussssssss lol
