what to do with my engine?

That's actually a decent mod list you have going.

Although I still do not think you need to spend money on a MAP Stg 2 head. This is just my opinion. If I was in your shoes, all I would do is get a very mild port done (basically clean up any casting imperfections), and get some basic spring upgrades like Crowers. Anything more then that, I personally think it's money spent better elsewhere. For you, I see you don't have a wideband on your list. I also see you're on an ACT 2100, which I forsee you running into issues with at that power level. You're considering E85 but still on 680 injectors. That, and possible fuel pump upgrade, are both things you need to take into consideration if going to E85. All of those things I would definately consider money better spent IMO.

But looks like you're going to have a fairly solid setup, good luck with it!
