I have my 3770k delidded, and I was wondering if direct die makes an even bigger difference. If there is a difference, how much would there be? And how would I go about mounting my H220 directly to the die?

Honestly, I'd say mounting it to the direct die is a bad choice, because of the fact that it can crack the actual die of the 3770k, and that's another $300 out of your pocket. I don't think there would be much of a difference, at the most probably around 5 degrees.

As for mounting, I dont know if the H220's spacing would even work with out the heat spreader.

I would say normal IHS lapped for the delid easily. I know that its tempting for direct mount and its really hard unless you have the naked ivy mount by EK. With the closed loops like yours, it takes a lot of time to get the pressure just right and make sure its evenly spread over the die. It can be done and I've seen it done but the temp drops are around 3-5C area.

If you want to know more let me know.

Well it seems risky to do direct die. I've been looking in to lapping my IHS, but im not sure how to exactly do it. Could you help me?

There is also a guide on the delidded club as well about lapping

and any delidding questions you got can be asked there as well as normal OT stuff
