Installed a set of Doug's D326 Headers. Fit great, look great - no complaints. The Delco starter is too long and the back of it hits a tube, so I bought a generic mini starter from Summit but that didn't fit either. Clocked it in every position available, but the problem is its too long. Before I just keep guessing, I'm hoping somebody else is running Doug's like mine and can tell me what starter worked for you. For what its worth the Delco starter measures 8" from the centerline of the forward bolt hole to the back of the case, and the Summit starter measures 7-1/2".
