Something like this engine will get your bottom end moving!
Great build for the Evo is 9.8-1 to 10.0-1 with a EV27 or W6, good valve job with a port cleanup, will do most everything you need. 80/80 is very obtainable.
80" Evo can do a lot, 89" Evo can do more, still very reliable and can take anything thrown at it. 100/100 is obtainable with the right parts.
S&S 124 and Ultima 127 is another world, still feel the numbers the S&S 111 is logging now is off the charts. The 124" and 127" have a lot left in them that can come out, sky is the limit until streetabilty takes hold, bada$$ when getting close to that point

Yeah i was looking at a S&S 89" stroker kit with cams and headwork... i think that would do it.. would anyone recommend higher compression aswell?

100/100 would not be bad at all..
You can run your compression up but need to head towards a later intake closing cam. Didn't recall if you have a bagger or light bike, 10.2-1 is max for a bagger with around a 40 degree intake closing cam, dropping back some on the compression is safe on hot days, heavy loads or 93 octane not available being a bagger once again.
Hotrod on here knows the light bike compression - intake closing ratio for a light bike well, he would be the one to consult if you want to know the fine line.
Note: that 89" S&S flywheel can take anything you throw at it, just do your money numbers and see how close a smaller engine build comes to a S&S 111, it's hp/tq numbers are amazing out of the box

I ride a electra glide 1996.. someone told me to keep the compression under 10 for reliability...
Rev Performance has had the Nikasil cylinder out for a while resulting in a bigger bore, doesn't seem to be a popular product for the Evo. Few members have ran the 85" and worked for them, history posts show some haven't.
