EDIT: My longtubes + prochamber fit perfect as well - no complaints. Also, his longtubes went in and bolted up great - we had them in and bolted up within about 20min. Using the good ole' Grady bolt and lockwasher. FWIW, I've got the same bolt/lockwasher combo on my headers and they haven't had any problems. Heatcycle them and retorque and you are good to go.
Back on topic -- Sage2k got his prochamber used - not sure if it's really a 94-95 piece or a fox piece. I think he's got it with him because I can't find it in my shop. If I do have it, it grew legs.
Once he measures it, we'll know for sure.
Screw an exhaust I'm still trying to talk him into running open headers around town lol. Hearing is overrated.
