Trick flow

Man I hate to be a "negative Nancy" on this because I love the Trick Flow product line but boy they stopped short on this one.(190 cc runner) I can only hope they follow up like they did on the big block head starting with a 240 cc runner and then offering the 270 cc head. This head is begging for a 2.05 valve in its current form and ProMaxx heads can be bought cheaper and with some added expense flow 315 PLUS. Looks like my 360-1 heads will get at least another year till I can posibly move towards an Edelbrock Victor head.

Please explain how the runner size has anything to do with flow volume.
