It really was the lack of room with the Big Tube Hookers on the Hemi. No room at all and the smaller factory starter just touched the headers and that is not a good thing with the heat. I thought about wrapping the headers in the starter area on the headers and using the old style starter but I ended up wrapping the headers of the Big Tube Hookers with the Rocky style starter and that worked great. I have a little smaller tube Hemi Hooker Headers on the motor now and did not use the wrap but used the same Starter and there is plenty of clearance for the starter and I do not have to pull the header off to get the starter out. I like those new Style little starters, I can put up with the new noise that comes out of them.
