I made a special collector with some exhaust adapters I bought at Canadian Tire. I started with a 90* bend and heated the s#!t out of it and bent it six ways from Sunday LOL. The real solution is to slice asmall section out of the collector and reweld it so it no longer smacks the I beam. Then, if you're like me, you'll want to heat the section of the collector that runs at the back of the starter and flatten it out enough to clear even the largest starter (mine is for a Bronco with a 351W). It would not hurt to make a starter heat shield out of some sheet metal and get a roll of header wrap too. I literally toasted a couple of starters before I realized that heat soak was destroying my starters. $239 is not bad for a set of headers, but if you buy the Hedmans be prepared to do a little modification.
