Question for the porting pro's
I will be doing a set of 110" drop in cylinders with -7.2cc dish pistons and Andrews 54 cams on my 2016 Road King.
The bike has SE slip on's and a SE air cleaner. I've tried the gutted cat head pipe and we just didn't like the sound. (too loud and barky)
The bike now has the stock head pipe with the cat still in and that is going to stay in place along with the SE slip on's..
So, is it worthwhile to have the heads ported or not?

porting is important for any build,i will agree that using that ex system will be leaving a lot on the table,but porting is important anytime your going to a larger CID build.a different ex system would be a very good idea though

If the OP is doing the porting, start studying now as it will take at least a month to get somewhat mentally prepared.
You need seat tools, valve tools, just for the beginning, along with all sorts of other cutters /grinders.
Remember -the valve job is part of the porting process.
Perhaps the most important to get all the angles correct and ratios in tolerance for what you are aiming for.
Or be brutally honest with yourself as to what you want. Then- for the end result and talk to a known head porter.
Also, ask about their timeline as some are backed up 6 months and more.
I don't usually recommend vendors , but will tell you if they suck.
I would at least talk to Hillsdale (scott) he advertises on here and answers forums stuff from time to time.
Don't EVEN consider a run of the mill machine shop if you are looking for real results.

Porting will help.. Would be better to use an SnS570 with the extra exhaust duration if you want to use the stock headpipe with cat.

Good suggestion from Max.^^^^^^^
Be aware that the cat will throw off unwanted heat, however.

wasn't aware the OP was doing his own porting,if this is so,i would strongly advise against it.probabley 95% of DIY porting we`ve seen here either dosnt do much over stock heads (very minimal taken out) or turns the heads into ashtrays (way too much taken out,especially in the wrong parts of the ports)
No. I'm not going to be doing my own porting, nor did I ever intend to do so.
Yes, I know the current exhaust system will limit performance and that's a trade off I'm willing to accept.
I like the current noise level and don't agree with the "the louder the better" crowd.
