440source Stealth head review and flow numbers

I figured I’d throw these in the mix.........

Cnc ported 906 also tested on EW’s bench, so in theory........ apples to apples:

Lift——-I/E
.100— 69.8/56.4
.200—124.4/105.4
.300—184.3/142.2
.400—236.0/168.8
.500—275.6/185.9
.600—274.9/196.7
.700—277.2/204.0
