Ported Edelbrock versus W2 out of the box !

Slight hijack......
The tale of two flow benches.......
Similar capacity benches, operating on the same basic design, but not the same bench manufacturer.

Intake:
Lift———A/B
.100—-70.5/67.5
.200—139.1/142.8
.300—203.2/207.6
.400—237.5/241.2
.500—252.8/256.1
.600—255.5/260.6

Exhaust:
Lift——- A/B
.100—-76.1/57.1
.200—124.3/111.0
.300—159.3/150.0
.400—177.4/167.1
.500—179.3/170.8
.600—181.4/174.4

Just in case it wasn’t clear....... this was the same head, tested on two different benches.
Two benches that are of the same design, type, operation, and flow capacity....... but made by different manufacturers....... and in different locations, run by two different operators.
