Here's what I used...
If you want to use a wrench, its gonna be big.
At least bigger than my sets have.

Buy an 02 sensor socket, not too expensive and much easier IMO. If the channel locks don't work out use the socket, channel locks worked on my old LT1 though. Good luck.

Seriously, its what I've always used.
Only reason I mentioned it is cause if you have a basic toolset, you PROB have on of these.
I think that thing gets them plenty tight.
I always wonder if I'm totally hacking my stuff up, I dunno, whatever works.
