Hey everybody -
So I got an exhaust leak and it's driving me nuts, so I guess I'd better get to fixing it. I think I have some options here, and I'd love to get some opinions from some of you guys who've wrestled with headers before...
This is a 1968 GTO and the block is a YC code out of a 1968 290HP, 2bbl (out of a full size, probably a Catalina or Executive).
The leak is in the header gasket - I attached a picture. It's right in the center ports. You can hear it, feel the gasses coming out, and see the area that's spent (see pic).
I've read everywhere about what a pain in the a&* it is to change headers - I'll be doing this on my back. So I was thinking - the headers are okay still (hooker long tubes) - might I be better off just unbolting and swapping out the gasket, rather than trying to replace the headers entirely?
If I unbolt them (assuming that goes alright) I'm thinking I can drop them enough to get the spent gasket out of there, get the new one in, and get them bolted back up - think that is doable?
It looks like I just need to get the steering shaft out of the way to get to that one bolt tucked up in there (by #5
) - sound right?
I'm a little worried about cracking those old bolts...should I be worried?
Or....should I just go for it and replace the headers altogether? The Hookers on there are flattened out on the very bottom from scraping - no holes, but beat up pretty good. But then I'm worried about repositioning the brake proportioning valve - the Hookers are RIGHT up against it. I don't know... I'm thinking dont screw with it since they're still at least okay...
What do you think?
Thanks for any insight or input!
See attached pics....
