You think rusty and other that taught you doesn't understand.
Possibly? were not talking crazy big ports and super low velocities on a super small engine revving ridiculously low rpms.
There's gonna be compromises, dudes building a low cr performance engine there compromise number 1, is the gains worth the possible losses is generally the question the OP needs to answer.
Can I ask you a question what is the ideal port cc, velocity fps and cfm for a streetable 318 with a peak hp around 5250 rpm, and what's closer stock 318 head or 360 head ?
Shouldn't you know before making the argument ?
