I have the 1 5/8th BBK longtubes with stock heads, stock WORN OUT motor mounts, and a solid transmission mount. No rubbing or hitting anywhere, but the BBK H pipe was a PITA to get on there as the headers didn't line up directly with the H Pipe but once I persuaded it I was able to bolt it on. Mine is a 92 coupe with a T5.
I also had the 1 5/8" BBK headers, with TF TW heads, and had no issues for a long time. When I moved the engine back 1", I then had issues with the BBK headers touching the steering shaft, which I corrected with offset rack bushings. I'd dimple the firewall with a hammer to create clearance if that made the problem go away.

Stupid questions first.
Used or new headers. Are they for a stick or auto. Headers for an auto are wider. If used, did you check to make sure the headers werent bent.
Is the engine sitting straight and centered? Check to see if your frame or k member is jacked.

BBK 1 5/8" Long Tubes in my '90 5-speed coupe. I have both Energy Suspension Polyurethane engine and trans mounts. Not issues at all. If my headers are running close to anything, it's the starter.

I run gt40 3 bar head and bbk full length headers with a tremec t-5 hd. Stock motor mounts and 86 cross member for trans. so i can have duel exhaust. i have BBK H pipe with hi flow cats and an x pipe all cnc high flow series and ive never had any issues with ether mid pipes. ive pulled my motor numerous times to change parts and have never had any issues touching. Are you the first owner of your car. Its possible the person you bought it from has damaged your car in the past. are not a lot of people out there tell you the answers if you dont ask the right questions. you get the guaranty until you cant see the tail lights anymore. i could take pics if you want on how mine look to show you that mine arnt even close to the firewall. But an idea you could heat metal and use an old oil filter to give you a nice concave grove that wouldn't appear out of place
I don't believe the car was ever hit. All the panels have the original VIN tags, clean carfax, and straight body lines. No signs of any body work, original paint in the engine bay. If you could post a pic that would be great, and I will as well when I get a chance, probably tomorrow morning. I'm thinking it must be the motor mounts... For a car this clean I refuse to purposely dent it. I want to just make it right.
