I have Edelbrock TES headers and I am trying to disconnect the passenger side header to allow for more space to remove the lower head bolts. What size are the bolts that connect the header to the Y-pipe? My car is positioned so I can't jack the front-passenger side up to get a good look. I can reach it (barely) but can't tell if I have the right socket or if I need a deep socket because the sides are hitting the flange.

 

IIRC they are either 14mm or 15mm

That's exactly what I needed to know. I think I'll need a deep socket though. Do you remember? Thanks
