Alright I got it to idle but now the whole engine and car is shaking like really bad when its idling and I have massive power loss so I'm guessing more vacuum leaks? And also I have a coolant lead somewhere like on the backside of the head but I can't find a coolant hose back there? I need some help guys so anything would be greatly appreciated.

a vacuum leak is not going to make your car shake, ill see what i can gather from my notes... sorry i didn't see this post

the coolant lines on the rear are the feed and return of the heater system

Could the timing being off be the reason why the car shakes when on idle? I know that there's a penny sized hole in the back of my header from the EGR pipe not being in there anymore but the nut is, could that have anything to do with it?

Man thanks for your help but I think the block is cracked. Water is pouring out of the the exhaust and EGR piping hole in the header, I timed the engine and saw no improvement and it can't be a cracked head or head gasket bc they're both new and checked out. So my only guess is that there's a crack in one of the cylinder walls or in the block somewhere else, man I just wasted $500 rebuilding the engine to get to this, I'm pissed. If you could direct me to a good block to buy though I would appreciate it.
