Problem after 1G head swap

[SnowWhite]

Alright...me and my buddy, Frontwheeler, just completed my head swap in my 2G. We put a 1G head and 1G intake manifold on the 'ol beast. I have a problem is that one I have really rough idle. My car goes between 500 and 900 rpm's constantly and it sucks. Makes it sound like I have aftermarket cams, which is not a bad thing, unless you don't have after market cams. I was just wondering if many people had the same problem once they had their swap done. Or any clues on what it could be.

Also, my driver's side shock/coilover squeeks louder than held whenever I turn that direction...could it be one of them is shot?

Sorry that these two questions are totally off base of each other, just looking for some assistance.

did you pressurize your intake looking for vacuum/boost leaks thats where i would start. simple and quick test.
