Placement of pull-up bars for pike pulls

[Ben Sommer]

I got two cheap doorway pullup bars so I can do pike pulls. They’re semi-permanent so gotta pick the right spot to bolt in the brackets, which for pike pulls appear to be just adjacent to each other 

I’m in foundation 1 so pike pulls are the only moves I see that absolutely require these bars.

Are there other moves that will also require stall bars, and will they require different placement than that for the pulls?

p.s. I am already accomplishing elevated bridge and pike pushups by putting my feet up on a windowsill
