Intake manifold gasket, anybody have this?

Intake manifold gasket, anybody have this?
I finally decided to fix the oil leak in my 94 z28, you know, the infamous sealant leak in the back. Purchased a felpro gasket set and installed everything as per the factory service manual. Took my time, did it right, changed out many old vacuum hoses (some where getting cracked), started the car and it ran like total crap (actually barely ran at all, ran great before I started), seemed like a massive vacuum leak. Analyzed it to leaky fuel injector O-rings, replaced them with a/c delco ones (they actually were slightly bigger than the felpro ones), car runs a little better but still barely able to run. Vacuum leak still exists, (as evidenced by no power brakes almost at all).
Anybody else go through this, I'm, looking for ideas before I tackle this again.

If you can't hear it, try a smoke and see if you can see it go into the engine at the leak. There are several you tube videos on how to install the intake manifold. When installing the manifold, it's easy to disturb the RTV on the rear wall of the block.

I would agree with the "triple check" advice. I recently just did the work you are describing. Took a long time to find all the pics showing proper vacuum routes, they can be a bit confusing. Could you expand on what you were talking about when you said "the infamous sealant leak in the back". I actually just developed a leak in the back after i did the work.

BTW, A leak there will not cause a vacuum leak. It will let crankcase vapors and/or oil out.
