i would have to disagree about the 4.3 head flowing worse than a siamesed ported inline. our worse thing going against us is the siamesed port.

Found the flow of the stock 1991 4.3 V-6 1.94" intake Syclone head.

The stock heads flow:

(164 @ .500" - Stock)

How does that compare to the 1.72" or 1.94" siamesed head?
