I have had them installed on my boat but not fully tried them yet. I went out the other day to see what they could do and discovered that my throttles were not adjusted properly. I will let you know once I get them adjusted. So far, I can only get my throttles to three quarters.

No, my motors were 502 MPI with stock mercruiser exhaust. I installed headers and Arizona upgrade at the same time, so I don"t know how much increase was the headers or the upgrade.

Do you have the phone# or web link? I am interested in the kit for my 502 Mag as well. How hard was it to measure up for the CMI's I was lookin the the diagram sheets today to measure for the exhaust?
