For some reason after I installed the full Bassani exhaust on my L the header bolts keep coming loose, I try and get them as tight as I can, but I have to do this again tonight for the third time and was wondering if anybody else has this problem. Is there anything I can do to avoid this again? Thanks for your help.

 

I haven't had this proble with mine and I must take them off once every 3 or 4 months.

Maybe to much antiseize?

 

Look for a set of Stage Eight locking header bolts from Summit or any racing supply place. I had the same exact problem on my 93 LX after putting headers on it.
I installed the lockers, no prob. again!,
Not only that but they look cool too!
They're about $50.00 for the set of 16...

Good luck!
