Hello and help if you can. I am looking to install a set of nearly new SE 255 cams in my 09 Heritage and have a few questions. #1, will I need to change the pushrods to adjustable or is the base circle close enough for the stock rods to work? #2, I have a stage 1 and a SERT map but I can't seem to find a good map with the SERT files that call for just the free flow AC and pipes along with the 255's. Can I use something else that would keep me out of trouble. I have never had the thing dyno tuned and it runs awsome as is. Hopefully this question is not somewhere down the posts as I have not found anything on this issue. Thank you in advance..
