Re: Header - Steering box Clearance
True, If you do have the incorrect mount stands , you will have problems. You should not have to shim up one side to clear ps. Go to David Pozzri site and he explains it well and even list the part # for the mount towers.
If mounting is correct , I will say that some headers and Hedman is no exception , will hit the ps box. I had Hooker 2451 and they cleared by 3/4 " but the hung down on driver side. After living with it for 15 years,,, I opted out for Thorley 376 1 coated. They fit perfect but the collectors are 2 .5 " which does not matter to me as the remainder of my pipes are the same size. They are 14 guage tubing, 3/8" flanges and they send you the collector hook ups that dont use flat gaskets that leak. About $520 delivered. Still a good deal. Do your home work first.
One other thing , later sbc and bbc mounts are the same, 2 1/8" from bolt eye to flat plate. Earlier ones are 1 3/4. They are easily mixed at the parts counter.
