i got it out. I clamped down some vise grips as hard as I could on the lip, prayed, and smacked the vise grips with a hammer for a good five minutes, then i put the vise grips higher up and I was able to twist and pull until it popped out. It's about a 1/2" long from the lip, it's an aftermarket dipstick (or it broke off on the inside dosn't look like it though). I think it's still usable but the lip is a little damaged so I think i'll get a new just in case. Thanks for all the help guys, installing these headers is a real bear, I ordered the wrong header bolts from summit so now i need to go buy some cheapies at auto-zone to get it done. Who knows what else will happen next.
