Trust me, the last thing I wanted to do was beat on these headers that I just spent over $700 on. The engine is mounted using schumacher conversion mounts so I can only assume they place the engine in the correct location. I talked to tti about the clearance issues and they politely told me "they should fit". Either way, they are in the car and have been for almost two years and I have no complaints. I must say, they are way better fitting headers than the old cppa pieces of crap I used on a big block demon back in the day.
