I'd recurve the dist. It would probably be better with 12-16 fegrees initial and about 38 total. That would be a nice starting place. 46 is too much. you may noy have any ping for a number of reasons...long overlap cam, low compression...or you may not be hearing it over the exhaust. It will also depend on how quick it comes in, but I think 46 is too much regardless of when it comes in.
