One of the biggest things I found - even with the 2 inch they just built me, was they don't clean the ports. I mean that they do the welds on the inside of the primaries (so they look pretty) - which might be as thick as 1/8 inch on each side. That reduces your flow passage greatly. I ported all the primaries with a diegrinder and now will have true 2 inch ports from engine to collectors. You know what the weather was like today, so I am still waiting to scream it a little!
