1.03 torsion bars vs Dougs headers

I had the same problem, and didn't want to dent a new set of $900 headers. I was able to mount the headers to the head, then get underneath and pull the collector over with a ratchet strap, just enough that when released created an 1/8" gap. Probably not the best way, but it worked for me, I have clearance, and no leaks.
