Small vs mild vs large streetport

Cool, good info. Yeah I read that you don't really want to drop the port abruptly, like basically end up w/ a wall at the end I guess? Which is basic common porting sense, but is there a specific angle it like the best? I need to find some pics of what I'm talking about. I think it's the big end of the port.

Are there better intake manifolds out there for the 13B? I don't recall seeing much in the way of aftermarket intakes.

Edit: Here's what I'm talking about on the ports. In this post the guy says you shouldn't cut straight down at the big end of the port (like he did in the 1st 2 pics to find the water jacket). Does his porting look right?
