At your sub-novice level, might I suggest that you kindly forget about openings and just learn more basic things like not how to lose your queen in the first 3 moves and such.
Wheareas you, at your lofty level of 1321, get to ask about openings in all your threads so far?

Anyway, as to the original question, I'd suggest that very few people play King's Gambit with the endgame in mind; it's about opening things up quickly and aggressively, and ending the game before it reaches an endgame. At least, that's my view of it, at my modest level.
What will be the endgames of this two openings is the king's gambit is anvantage or the evan"s gambit?
