Hi guys, I'm putting a set of hooker headers on my 85 Trans am, and I can't seem to get just one of the middle bolts on the passenger side, by the number six tube. Every time I try and get it in it feels like it's cross threading and I know that's not good. I tried dimpling the header to maybe get more clearance but that didn't help either. If I can get all of the other bolts down really tight is it ok to not have that one? Thanks.

 

If you have all of the other bolts tightened down already, you might try loosening them a little so the header has some play. I had the same issue with mine (poor construction maybe?) but once I got all the bolts started I was able to tighten them all fully. Having an extra set of hands really helps!

I don't know how safe it is to run headers shy one bolt. Maybe with high quality gaskets you can get away with it for a little while. Header bolts do tend to back out over time though, so I wouldn't suggest it myself.

 

Start them all before getting them tightened down. Maybe install that one first.

I personally like these bolts because they have a small head and allow you to get a box end wrench on each one.
