Hey guys, I just replaced the driver's side header gasket on my 1995 Mustang
351W (with short tube hooker headers) and after I was done I started it up and it was smoking from the header, didn't smell like oil, more like a burnt rubber or composite smell. Is this normal when you install a new header gasket? I'm sure I tightened all the bolts correctly. Maybe the gasket was just seating? Any input would be greatly appreciated.
