Good numbers for sure. Question though, why do the wot-tech manifolds stay lower at the begging of the exhaust stroke

I saw that and was wondering the same thing...

Those are numbers without manifolds. Probably the valve job on the .050 and .100" lift flow numbers.

Stock 3400 Intake = 111.4cc
WOT-Tech Strip Intake = 113.5cc
WOT-Tech Race Intake = 119.4cc
MMS Stage 2 Intake = 117.2cc

Stock 3400 Exhaust = 70cc
WOT-Tech Strip and Race Exhaust = 72cc
MMS Stage 2 Exhaust = 76.2cc

WOT-Tech Street/Strip heads outflow MMS Stage 2 and have more velocity on intake and exhaust.
