Kyull,
I think you sold the Offy & got a Clifford?
I think the Offy will distribute the A/F better that the Clifford manifold because of the squared off corners.
I believe you are going to blow through a carb?
Plus I believe the Offy will build boost quicker & give you better throttle response. Also better overall drivability.
With the Offy being smaller ports over the Clifford, being you are forcing air/fuel through it, the smaller runners will not be really restrictive as some think it would be.
W/the Clifford, numbers 1 & 6 will get more fuel & 2 & 5 will run lean.
If you are going to use the Clifford intake I would run a devider in the ports to get closer to equal A/F delivery.

To get even better distribution, you would need to make a devider in the cyl head, but that drastically kills the airflow & would require to make your intake port windows a lot bigger to gain some of the lost airflow back.
