Squaretop manifold porting
 

Has anyone ported a square top intake manifold?
ive heard you can cut out the entire top section, what about cutting into floor of the egr expansion chamber?
Will be deleting the egr and will be boosted
(supercharger if it matters)

what would be the benefits of the larger plenum volume?
And maybe 1/4 inch shorter runners?
