Turner Shorty Headers

[schmidty]

Is anyone using Turner Shorty Headers in their M52 swap?
I'm wondering:
a) if they fit and how much clearance
b) can OBD1 headers be easily modified if you are keeping the engine ODB2? Would it be easy to have someone tap a hole for the O2 sensor? Is that all that would need to be modified?

Thanks

You would need to weld a bung onto the manifolds for the O2 sensor. This can be problematic considering the manifolds are cast.
