Switched coil packs?Rough idle! I did a few searches and came up with some info...but first, I recently finished up the engine and got it running but it is very rough and shakes, then jolts once in awhile. Doesnt look or sound very healthly! When i searched i found a thread about someone switching the coil packs to the opposite sides after a header install by accident, and had a rough idle and the same symptoms. Is it worth it to switch them to see if it humbles down a bit? Could it be vacuum leaks and what not?Its not a stock cam, its 224,228 .581,.588 and i have no clue how its supposed to run 
.
Thanks, Dave

Dave not an expert with cams, but I am sure someone will jump in who is.
However, no matter what cam you have, it should smooth out at some rpm and not miss, jump, or stumble.
If it does, I would check that your ignition wires are fully seated on both the coil and plugs ends, any broken plugs, etc.
As far as vacuum leak, put a gauge on it and see. High and steady needle should be at idle. Not knowing your cam, it alone could cause a low vacuum at idle.
Its usually the simple things that cause the majority of problems.
Good luck.
