Sorry, for some reason img tags aren't working on my post.
I installed your modpack with all the listed dependencies and NO additional mods, on a fresh install. That gives these two errors:

I tried every version as well.
Regardless of any mod versions I have tried I also get this error from py's petrochem:

Error was reported on other pages, some having mixed results and reporting disabling PCPredux fixes it, others say it doesn't. I disabled PCPredux and it did fix the second error. But you list PCPredux as a dependency so I'm not sure what to do.
I'm not familiar with the back end of things I simply tried various loads with different versions looking for a way to get it all to load error free. I'm super interested in trying this pack, appreciate a fix as soon as you can.
