What problems have come from the s&s cylinders? I'm shying away from the fm 107 because I've personally seen a set of cylinders that came from them and there was a huge wave in the middle of the cylinders. The engine builder had to send them back because they were so bad. Could have been a rare issue but I'd rather run a set of cylinders that were designed to be a bigger bore

Someone else to consider and just up north from you is Dan Baisley in Portland.
I went up and met him and was going to have him do some heads for me for my RK (little over ten years ago) but then had to go to Iraq and sold the bike (damn I loved that bike).
Check out his website, ....hmm, ....yeah, now you got me thinking

Baisley is one of the great no doubt.
Who ever you go with for the heads the biggest recommendation I can make is don't go cheap on them. Heads are the lungs and the key to the entire build.....the rest are just bolt on parts. Guy who does your heads should tell you the rest of the build so that everything jives together.

Their new cylinders look good.

Are you sure you're not thinking of the old long stroke 106 kits?
Compression is all about cam choice. What you end up choosing for cams will dictate what the compression should be set at. T man likes compression with his cams. As long as it's matched to the cams and tuned well you won't have a problem. My bike is 12:1 with some long cams and I always run 91 or 93, I've run 89 when that's all we could find in nh and never had it ping in the heat and traffic. It's tuned very well though.
You can get some really nice headwork for around a grand, you don't need anything crazy. Make sure the head porter knows what throttle body you will be running so he can size the intake runner correctly. You really need to make sure everyone is on the same page when you're dealing with multiple shops to avoid headaches. Feel free to pm with more questions.

Going to a DME 107"
Well after talking to enough shops I've been talked into going with a 107" kit. Leaning toward Dave Mackies kit with his heads and 598 cams. I want to start ordering other stuff I will need. I'm still running the stock compensator and I'm thinking of going with the SE comp (there doesn't seem to be a lot of good options). Also with the tensioner I'm leaning toward to baker attitude adjuster. Anybody have any input on those parts? I'll probably throw on an Andrews 30t pulley while everything is torn down as well.

Don't see a lot of info on Dave Mackie cams/heads, should be interesting. Those 598s have an intake close of 50 degrees, what compression is he planning on? Should rip in the high rpms and a bunch of compression should take care of the lower rpms.
SE compensator, Baker adjuster, Andrews 30T with a heavy duty clutch spring will be a nice primary side set up. Sounds strong.
Can't remember but you are going to check the crank run out, right?

I have a s&s 106" kit on our wide glide. Using the S&S585 easy start cams, cleaned, polished throttle body, stage 4 head work. We got 114.8hp with 112.3 tq..
Hits hard at 3,000 rpm's and up.
I was looking for hp but got better tq than I expected.
There is so much out there now it is really hard to make a decision. I am a die hard S&S guy. Been using their parts since way way back with no problems.
The S&S 585 cams are one of my favorites. You can do a build in any direction with them. HP or TQ it all depends on how much you want to spend.
My 113 with S&S gear cams with stage 5 head work gave me 124.8 hp with 138 tq.
