I put a set of intake gaskets on my '94 350 mag/alpha today and now its running like crap. Runs rough and doesn't sound right. As far as I can tell, everything is hooked back up as it should be. Timing is set at 8 deg BTDC using a light, and I'm holding 18 inches of vaccum at idle. Help me out here guys.
This is what it sounded like before with it idled up a touch:

Also, my starboard exhaust riser gasket was leaking, so I ordered a new one from sierra.
This is the one that it had on it:

What is the purpose of the restricted gasket? As of this second it has the 2 different gaskets on it, but I wanted to find out what the purpose of each one was. I can tell ya the exhaust riser is ice cold now, even with it running. lol

Well...the only thing that you changed was the intake manifold gaskets. I vote for vacuum leak. While it's running try spraying WD40 along every gasket...if the engine sound changes there's your leak.

It holds steady at 18 inches of vacuum at idle. Is that not sufficient?
