Dave, thanks for the info. I will be sure not to go to far, just open it up a bit to square the port as much as I can with out the ring issue.

Bill, specific question? No not really, Just looking to collect data from people and their trial and errors. Im not looking to make reace engines, just looking to try and get the most out of a conversion across all RPMs.

Av8tor, thanks for the info. Thats what Im looking for, kind of like that chart you did in your one post. Just geared more towards the style of engines I mentioned. I know the port timing numbers directly affect it but anything on duration?
