o2 sensor housing hardware

[Aproductions]

I was wondering since I have a holset and a punishment racing o2 housing, do I use o2 housing studs/nuts or bolts....or two of each?

I would use what ever made the install easy.

I use (4) bolts Alex, the reason being is if you've got to remove the o2 housing and don't want to pull the turbo you don't have clearance issues. If you had a stud on there you'd have to figure out a way to slide it off the stud and the alternator, OFH, and o2 sensor all seem to get in the way.
