Header Bolt Question

Header Bolt Question
Alright if anyone was following my other thread, I posted how my used MAC headers didn't line up to the bolt holes on the passenger side.
Well I was able to file it out so I enlarged the holes so they do line up now, except for the 2nd bolt hole on the passenger front of the engine (read as, right above the #2 spark plug)...
If I leave this bolt out, will I develop a header leak? How about if I goo it down real good with the RTV Gasket? I have no idea how I'm going to make it fit otherwise, as I can't really make that hole bigger as it's very close to the primary tube....

I was thinking about this and possibly I could file all the other holes wider so I could slide the headers forward that 1 centimeter (or less) to make them all line up? I can't believe this, that the headers warped with the previous owner and don't line up....This has given me a problem for like three weeks. *sigh*

If your flange is warped causing the hole mismatch your never going to seal. If it was me I'd bite the big one & buy a new set of headers! Working on these cars is a pain & leaks will make more work.

I agree. Headers tend to warp a little bit as they get older but if it's so bad that you can't get a bolt in then I suggest buying new ones.
If you do get new ones get a Felpro gasket and line it up to see if it matches before trying to install it.

Well now i know not to buy used headers. I think I'm gonna file the holes so they widen up and all fit in.
I know what you mean about more than one hole, but trust me, I'm using the right ones.
If these give me a problem I'll wind up getting new ones and selling these headers. I can deal with a header leak for a little while (if that's what happens).
