If you are looking for opinions, here you go.
1 - First , Need to understand your goal and endgame.
2 - I would take the heads, cam and intake and put it back on the shelf and put the stock style heads back on and maximize that combo first. You will most likely be happier in the end.
3 - Stage 2 heads really need a radically different combo to extract any benefit so unless you are willing to take that path I would adhere to step 1 above. Based on that cam and assuming you are running modest compression you are better off with stock style heads.
4 - Stage 2 heads will work but not worth the compromises and extra effort in most situations.
