Chevy had problems with leaky manifolds on their inline six engines due to the design. Several years back I started installing them with Ultra-copper RTV. I place a thin bead (about 1/4" thick) between the gasket and the manifold, then bolt the manifold on and tighten the bolts. Inspect for gaps, and redo with more sealant if there are any. Don't start the engine for 24 hours, allowing the RTV time to cure. At that time you can trim away the excess with a sharp knife or razor blade if desired.
I haven't had a leaky manifold since.

Hey, Guys, what happens if you don't turn the "shinny" side out against the manifold?

Don't tighten the bolts connecting the two manifolds together until you have tightened the bolts between the manifolds and the head.
Forgetting this will result in cracked manifolds and leaks.

Ok - let me try again - what I meant is: What happens if you turn the "shinny" side in, against the head?

I put them back to back so that there's a shiny side facing the header and one facing the head. Works fine. I don't see why you couldn't do that with your I6 gasket. Matter of fact, that's what I'd reccomend doing...using 2 gaskets back-to-back. | | |

Thanks, guys. Slowly, but surely, I'm learning. That's how we all got where we are today.  Lot's of questions and lot's of experimentation, even a few things destroyed in the process. Best if you can learn from someone else's mistakes. It's usually cheaper that way. I really like these forums where people are willing to share their hard-earned knowledge. Makes it so much better for those without as much experience to succeed. I would love to be in a position where I did nothing but advise people in matters such as this. Unfortunately, I have to keep some cash flowing in to support my hobbies.
