Flow bench data for b16a head

[Ramvtec]

Did some flow bench test on the b16a2 head here are the results, gonna try flow the b16b head and compare the differences, as you can see the flared entry port is the best, as trumpets on throttle bodies help the air turn the corner without slowing it down, if you didnt have them the air would have to turn a 90 degree corner which would slow it down alot, hope its a little help for the builders

Company in Canada did some flow test before and after their porting:

B16a2: 216cfm@0.450'' lift IN
173cfm@0.450'' lift EX

Now like you can see is only head...

B18c5/B16b: 248cfm@0.450'' lift IN
196cfm@0.450'' lift EX

nice i have the flow at 1/4 the valve diameter to, there might be some errors in that data but its not to far out i think.
