deja Posted March 6, 2007 Share Posted March 6, 2007 Sunday I posted http://forums.hybridz.org/showthread.php?t=119776 saying I had some clearance issues with the driver's side header on my LT1. Last evening I started grinding on the spacer. I took quite a bit off, more than I'd like but little by little the header got closer to fitting. Finally I could get a piece of paper between the spacer and header pipe. The just out of curiosity I switched the two headers side to side. Seems like Sanderson's quality control doesn't hold very tight tolerances. The other header fits with about a 1/16" more clearance. Looking at the weld at the port its obvious why. The second header is welded closer to the top of the flange opening than the first one raising the pipe at the bottom 1/16". I wish I had seen that before I started grinding. Hopefully the metal I removed from the spacer isn't going to be a problem, I don't think it will, there is still a lot left. Oh yeah, when the header is properly seated I have no clearance issue with the steering shaft. Quote Link to comment Share on other sites More sharing options...
SSflyer Posted March 7, 2007 Share Posted March 7, 2007 What do you mean by switched the headers from side to side? I don't follow... Quote Link to comment Share on other sites More sharing options...
deja Posted March 7, 2007 Author Share Posted March 7, 2007 They are block huggers, they are the same on both sides. Collectors are right in the middle. What do you mean by switched the headers from side to side? I don't follow... Quote Link to comment Share on other sites More sharing options...
BillZ260 Posted March 7, 2007 Share Posted March 7, 2007 Deja, reading this made me realize something!!!! When I started my new SBC in December, I tried to bolt on the exhaust that Mikelly had sold be to the headers I already had only to be rejected when the flanges on the exhaust tubes didn't match the clocking of the flanges on the headers... This might be my solution, DOH! Thanks Quote Link to comment Share on other sites More sharing options...
