this versus that head comparo on a 351W

[Boss 351]

What would be better... A set of Twisted Wedge heads and an RPM airgap intake or an old Ford 351W Boss intake with 351C heads?

Knock yourself out with head data - don't know about the intake, but I've gotta think a more contemporary intake is gonna better than the oem piece....

There is no such thing as a 351W BOSS. 351C BOSS (which I'll assume is what you meant), yes.

The answer depends on your application. Clevlands are great for upper mid-high RPM power. That 351W combo would make decent power all over dependignon cam.

If it's a factory 351C Boss intake and factory closed chamber 351C heads. It will flow equal, if not better numbers than those 351W parts. One thing to keep in mind, flow numbers aren't the end all and be all of power production. Port volume, combustion volume, combustion chamber shape, port velocity, carburetor size and tune, camshaft specs, compression ratio, bore and stroke all have significant impacts on the ammount of power made by any engine. Yo uhave to look at it as a complete package and in relation to it's intended use.
