Hey Mild - how old where you in 1996 ? I have a quick funny (to me) head story - while we are waiting for the OP of course.

Alright....I'm cleaning out some things and I open a big plastic tub I have marked with "1 chamber 4" flowmasters , BBC valvetrain." Wholly schit I say, this is from way back." I got those mufflers when Kevin Mclelland (I believe his name was/is ) the owner of Flowmaster had just moved out of his garage making these just several years back. Of more interest is a folder I made back then of receipts and quotes for parts for one of my cars. Quote Dart 320's $2880 Super Comp Ported $3550. Receipt for ATI 8" treemaster "soft hit" $850.00 . A ton of other stuff in their of course - front end clip, rims, tires, whole bunch of schit, the Power Glide with 300M input shaft, transbrake, yada, yada .
Prices on heads and some other stuff not so different today huh ?
Until, I found the receipt for the Procharger kit for carb. With the upgraded billet impellar it was like $1800 and change. Now they are like 5000 times that . LOL.
Sorry for the ramble, that box opened some flashbacks of a few million years ago. LOL.

Port volumes can be misleading. Port shapes differ from head manufacturer to manufacturer. A Dart 310 vs an AFR 305 vs a Canfield 310 are 3 completely different ports. Valve size and cross sectional area dictate velocity profiles through a port and that will dictate how the head will "work" on a given combination. There are two basic areas in a port to look at; the front of the port where the "pinch" is (minimum restriction area usually somewhere near the push rod) and the "bowl" area which is the area below the valve and up to the apex of the short turn. Some ports can have a lot of volume at the front of the port with a larger cross section, and smaller in the bowl area (like the Canfield) and some ports will have less volume and smaller cross section near the push rod and more volume in the bowl area...yet both ports may measure the same volume. A port with a smaller cross section and larger bowl area will have slightly better airspeed through the port and work more favorably on smaller or lower rpm engines while a port with a slightly larger cross section and more volume in the front of the port might work a little better on larger engines or smaller engines running more rpm.
