Agreed, I see massive ports on engines here at work, but they are 3000+ cruise and WOT engines. I thought we benefit from the high velocity of the smaller port. I had a set of 452s at work and they laughed at them. Even our 2.1L 4cyl has almost double the ports and much larger valves.
I thought I read somewhere about Bob Glidden (maybe??) using large port intake runners with smaller port heads to increase velocity. Hmmmm
