OBX flange issue?
Spent most of the day reinstalling heads, intake, etc. I am installing for the first time, OBX headers on my L98. Passenger side went up and bolts went in without issue. The driver side seems to be a problem.
Without physically verifying, I'm led to believe that the bolt holes in the flange aren't 100% correct. I can get a few bolts in, then when I try to add more they want to go in at an angle or not at all. I've tried multiple ways and and I still can't get any more than three bolts in.
Anybody with these run into the same problem?

Went with the Pacesetter shorties on my 96 LT1 and didn't have any problems like that, althought I can say from experience that while the Pacesetter shorties might look identical, there is a Left, and a Right side. LoL
You might end up having to enlarge the holes a tad where you can't get the bolts in. I have heard a lot of people talk about issues like yours when switching to headers.

If I had an acquaintance or a relationship with an automotive machine shop I might fit the header to a head on the bench first. There's no need to struggle with the "on the car" difficulties if you know someone. Even if you don't it might be worth a call just to see if they might accommodate you.
I noticed you mentioned you were installing heads etc SO I'd guess if your heads were done locally you should be all set!
