anybody who wants to by a pair would need to contact Rod Bloomer, i am sure he would give you all the info you need.
People have bought plenty of heads with way less info than is available to you regards these heads, just on this forum alone.
People have bought tons of sets of Trick flows. What info did they buy them with…track results? No..dyno results? No
Flow numbers? Yes, but so what. Flow numbers mean squat, extremely subjective.Seen anybody go fast with them yet? I havent.
My own opinion is this…. My next set of heads will be ones i know what they are capable of doing at the track. It would help my decision if i knew personally the talent level and history of who designed the ports….others can make buying decisions on what they find important. Each to his own
