The welded up heads are big massive ports for all out flow.
If you have the wrong cam, then it doesn't matter how it flows.
It all has to work together and until you understand that basic principle, you will finish second (last). You can't just buy a big port head and expect to be fast.
BTW, I heard Shaniqua gives discounts....

I flow all my heads and have also tested some of the members heads. My clements head has very mild porting in the area just above the seat port is left alone. I also have a MDB head with a lot of porting but it was on a early round port Honda head. The MDB head with 28.5 valve flows a max of 84 CFM @ ,400 lift while the clements with a 28mm valve flows 75 CFM @ .400 All heads I check are at 28 " H2O. The best flowing head I ever tested was a head MISFIT did that had a 32MM intake and 27mm ex. While I did not look at the bowl I could see the port up to the bowl was stock yet the head flowed 88CFM at .400 and was over 93 going to .450 but I hit coil bind around .430. My other heads do not increase after .350 to .400 lift. I learned from that head that the stock port can flow a lot of air and the valve and bowl area not so much. Stock heads are in the 50 CFM range at .300 to 350 lift + - % CFM. Would love to see numbers at different lifts others on here are getting to compare with.
the head i have now is a 32mm-28mm head done up my cheezy1... today i put a sleave in the head and epoxyd the hole then smoothed it out, i rode the bike and this thing pulls crazy hard through the powerband, it gets scary fast.. cheezy you got some skills...... but the epoxy thats in the head is chiping away, so im thinking about having another head done and just swapping the valves or just getting a 28.5/25 valve head done
You should have tested my unwelded and welded 32mm intake heads. My milder 28.5mm flows great for almost anyone, but the added work I do with the 32mm intake so far no one if close to my numbers. And I have flow numbers from 2007 at 100cfm.
Most of the heads I have had tested are very mild, which works well for mild engines. But if you're looking for all out power you know who to call.
