(Moved from a post in swap meet so as not to polute someone elses unrelated thread) OK I will bite. What did you find on the flow bench. I purchased a used BMP 800 Big bore and put it on a turbo. I was not impressed then it caught a ring on the exhaust port and took out the mag side. I had sent a pair of M7 cylinders to Millenium and had them bored out to 800 so I put them on. I didn't compare the BMP to the stock until after it ran awesome. I found the BMP cylinders where decked at the bottom 3.5 mm. That means I must have about .095 squish and all the ports raised back up 3.5mm, it is a little soft off idle but very tolerable especially since it runs so well on top. Is this what you are referring to? The lowered ports?
