Hey guys...I'm doing a 393. I was wanting to do AFR 185's, since I noticed they had emission legal ones. The shop who'll be doing the motor Suggested I go with the 205's instead, and that they can make them emissions legal as well. Can this be done? Also, When using the search on here I noticed someone said the 205's have a little higher port than the 185's. Will this cause problems getting the swap headers to fit or line up with everything right? It will also primarily be a street motor with occasional passes down the strip, it won't be a dog off the line with the 205's will it? I mentioned to them I wanted it to be something I could get in and drive out of state and back with no problems, and to pass emissions. They said with a mild cam it would be around 500 hp and completely reliable and emissions safe...sound right? I trust the guys fully, they've always been good to me, but I like to hear what people on here have to say as well. Thanks!
