Bob,
As I understand it, the Torker is a 90 degree, single plane manifold good for high RPM.
It's also taller than the stock manifold. So you would have to build a dog house engine cover
raising it up. The Rockwell manifold is the same as the stock one and is lighter weight aluminum.
Our engines seldom spin faster than 3000 RPM. So the Torker won't really help.

Here's the Rockwell manifold:
