Default 103 Build ???

I'm looking for ideas/suggestions on proceeding with more on my current build. Bike is a '16 Limited. I've already swapped the cams to S&S 551 gear drives, camplate, oil pump, tappets, quickie pushrods and running a D&D fatcat. My debate is whether I should leave it alone or throw more at it. I've thought about porting the heads, but then think if I'm doing that I might as well add some inches to it, valve job, etc, etc. For my guys that know way more about engines than I do, what would you suggest I do? Money is a consideration, but I want it done right and most important to me is reliability of what is being done.

Thanks in advance.

doing a 107 or 110 kit & headwork would be about all you can do,if doing the heads,make sure you pick someone who knows how to port for low end TQ & not just hog the ports out for peak CFM.wont work very well with the 551 cams

Thanks. I want the low end and the wet head leaves limited options for sure on what I can do. I wondered if that 551 was going to kill me since S&S says they don't like anything over 10 and the exhaust side closes earlier than other. I do like the gear drive setup though better than chain.

I did the FM 110 kit with LVL B heads and 777 and it runs very strong
