Lol, the Chevy High Performance article is what go me worrying in the first place
Well, it pulls 23" of vac at idle (16 degrees intial timing helps to make that big #), I've wound it to 5,500 and no mis-fires or anything else odd. The plug all look great too, nice and tan. Just trying to get some reassurance, I'm sure you know what its like when you're worried that something might be wrong. I think they were from a '99 pickup. I dinked around at the machine shop while I had my engine being done up. I remember the original seals were these ungodly big metal things. You had to pry them off the guide with a screw driver. Sort of like a big metal cap with rubber inside.
