Pro70, I think I know beautiful work when I see it! I just got my shorty tight-fit headers today but you guys making your own are really craftsmen of the top drawer. I am breaking in indirectly to confirm from the discussion above, that although I have a 2 1/2" collecter, I now need to sleeve it down to 2 1/4" for low rpm torque? Well anyway the AHC coating looks great on my headers and I hope I can keep it in the carb/timing range to avoid burning off the coating. The weather has to get better soon, maybe in a week or two because I have now accumulated a few parts which need to be installed, but it's been going down to the low 20s F every night and not getting above freezing until late afternoon and I think I will wait until it really is Spring before I start wrenching. Maybe two weeks will do it, but in the meantime thanks for putting up with my rambling just sitting at the computer hoping my immune system will finally beat the cold that just about everyone I know has had in the last month. Hey maybe Southerner is seeing the end of Summer down under? Well thanks for putting up with me and helping with a lot of tips that I would not have guessed. For instance DennyW says to use double gaskets with the headers (heated in warm water at that), does that not put more soft stuff at the gap and more likely to blow out? Anybody else favor the double gasket idea for headers?
