broke in the new engine- but need help

I broke in the new engine today, there were a few challenges gettin it all sewed up and running but I got it! It runs good. Pulls hard! For a 318 it will suprise the crap out of you..
So here's the question: How do you get the last two header bolts on the driver side tight enough? I got an exhaust leak on that side. I plugged the air injection holes with 1/4" pipe plugs, I hope they held well enough, they should have, but I have a definite leak, and I tried every thing to get those bolts tight enough. Can anyone help me? I was doing an eighth of a turn till I couldn't lock on the bolt any more, but they just aint tight enough, it's embarassing! These hands just don't fit in there very well, and I tried long wrenches, short wrenches, ratchets, straight arms, even tried a distributor wrench but it wouldn't work. Please, someone clue me in! Hooker 5901's have got to be some of the most common headers around, how do you all do it? My hedmans had more clearance, but they were flat as can be on the bottom, so I tried these hookers. Any one who knows the secret please tell me! Thanks, guys.
