Hi guys, some advice would be appreciated on this.......I am doing that S&S 106" build on my 08 FLHX (as I stated in another post). I am also doing the S&S 551 EZ Start cams, with the heads being ported and bigger valves and springs added (nothing insane, just a bit larger) and the TTS.....the porter asked me a question today and I was changing lifters and rods if needed....he was going to check out some research on MOCO quality of the lifter and rods but I wanted to ask here if i should or not; 1. Are the 08 HD lifters more than efficient for this build? 2. Are the 08 HD pushrods fine to use as well without going adjustable? Thanks for any advice guys.....I know I can upgrade as well but I would prefer to keep from spending more money if the HD ones will work just fine. Thoughts? Pipes. (ps; Glider, disregard the spark plug PM I sent you, got it figured out).
