I've been riding Harleys since 1976 and rode a 1976 Superglide from '76 to '99 when i traded it for a Vette. I Recently bought a Custom Chrome Hardcore II kit bike with the Revtech 110 inch engine in it. The previous 2 owners gave up on it because of the high compression and the compression release issues, plus burning up starters and cheap batteries because of trying to overcome the compression. First of all from what i can figure there are supposed to be two compression release tubes with either push buttons or screw out release tubes coming from the heads. This bike only has one from the from cylinder. I'm thinking i can remove these and plug the holes from the release tubes and retard the timing maybe 3 degrees and it should start much easier. Either that or change the cam to a S&S 256. Anybody have any experience with this "common" issue?

Welcome. I have reducers to reduce the second plug hole down to take the inexpensive 10mm compression releases. Its a tight squeeze but it will fix your starting issue.

I Ended up retarding the timing three degrees and adding a much stronger lithium ion battery and that fixed it for now. Thanks

A cheap but overlooked part of the starting system- cables.
Stock gauge, what is it, 4? suck. Even 2 is not good enough sometimes. It's a bottleneck of the electric delivery, sabotaging a good starter and battery.
I went with 1/0 vs 2/0 for all my builds[ a finger thick] , custom cut and crimped in a marina store. Indeed the space has to be taken into the account.
The ground attachment- one of the starter mounting bolts seems the best to me, if possible. some people use double ground cables- but with my gauges I didn't find it necessary.

Yeah that was my first thing to check was the cables and ends and loose bolts etc. But everything was tight and brand new like the bike with 2/0 cables. And it is tight for space with the wires because of two LED Light kits someone put on the bike. It's working right now, but the weather is warmer and conditions are fine. Thanks
