Small port heads, big port intake. How bad?

Like i said before. the large port manifold will slow air speed down......when air is slow, fuel drop out of the air stream, and runs into the cylinder as liquid fuel(only vapors are flammable!)

And, "TURBULENCE",..... It's like a "WET DOG" It Shakes all the fuel out of the air!

You will gain performance with the small manifold, compared to the large, Even tho the "large port" is more attractive.

JMHO.
