Hi Silicon Lottery!
I plan on deliding my 4790k and was wondering if you would be willing to share what epoxy you use to re-attach the IHS and what liquid electrical take you use on the resistors.
This is similar to what we use, but comes in a smaller size:
Liquid electric tape
Black Friday is coming up, and we're going to have a really low price on delidding ourselves if that interests you btw.

IMO, you shouldn't use an epoxy to permanently reattach the IHS. It creates a small gap between the die and the IHS, which is what causes a lot of the heat problems in the first place. Put a good liquid metal TIM on the die and lay the IHS back on top. Pick up some liquid electrical tape and put a thin layer on the exposed components on the PCB. Then reinstall the CPU back into the motherboard. Be sure to hold the IHS in place as you lower the locking arm.
If you use enough pressure when drying, there will be no difference in temperatures compared to just letting the IHS sit free. There won't be a gap (at least not nearly as large) like there was before delidding, I've tested this dozens of times.
If the gap is a big concern to you, you could paint a small amount of silicone on the inside of the IHS like I've shown in the picture below. The silicone will be squished down once you put the IHS back on, so it should be the same as letting the IHS sit free.
