Cam 180 off? Not possible, if it looks like it is, just keep turning the crank and after 1 revolution everything will be lined up like it's supposed to be. You could in theory put the crank dot at 12 o'clock, and the cam dot at 12 o'clock, 1 turn on the crank , and the crank will be back at 12, and the cam at 6.

If the plugs didn't spark at first and then they did after drying out then they are fouled and are no longer any good.
This is my last post in this thread and its obvious you don't want to listen to everyone trying to help you so have fun tearing your motor down again.

Detroitmuscle - Did you actually switch the coil packs from the passenger side (4 per bank) to the driver side to eliminate the possibility of an ignition misfire? If not you should. Also, you should have someone check for any trouble codes (pending or history) and post them if any show up.

I hooked up my HPtuners and the only code I got was for the A/C clutch and I don't know what that would be. I don't however think'd it effect the car starting. I kept the coil packs on seperate parts of the car when I took them off, so your saying you want me to still switch them from passenger side to driver side? I know they are on the side they started on and I didn't think that I would have to switch them thats why I never did it. Sorry if it doesn't appear as though I'm listening but I checked the damn electrical up and down.

Ok well this will settle it, I already drained my coolant and removed the crank bolt so I'm not gonna turn back now to try the coil pack thing. I will just have to remove the water pump and the timing cover, not everything, and see where the dots are. Once everything is back together I will try to start it again. If that doesn't do it then I will switch the coil packs from driver side to passenger and visa versa. Thanks for all the help guys and hopefully this will be it.

Ok, but you realise that a cam cannot be off 180 degrees. You can put the dots lining up at 6 and 12 or you can do it at 12 and 12. It won't matter. Now if you have something like 12 and 3 you have some issues. Your cam could be ground severely wrong and i suppose it could cause your issues.
Basically what I'm saying is if the cam is ground correctly and you haven't messed with the crank sprocket (which would be set at tdc from the factory) and you have the dots lined up it will run normally. Do you have your a/c belt on?

Yes I have the ac belt on but I'll have to recheck it out. What I meant by being 180 degrees off is that, since the crank gear dot is a 12 o'clock both at tdc and bdc that I installed it while it was at bdc. The install guide on LS1howto.com does not specify being at TDC at all and thats is where I might have gone wrong. Unless it doesn't matter, which is weird to me.

I had my mechanic friends working on mine so it's a bit fuzzy how the fix went.
Here it goes. At first I think they unplugged one side of coils from the harness to verify the one that was backwards. If it didn't backfire when one perticular side was unplugged you have narrowed it down to the problem side. I believe that once they dissconnected the bad side, it tried to run without backfiring. They then removed the one whole bad side of coils bracket and all.The order of the coils mounted on the bracket was reversed thereofore firing out of order.When you switch from 98 to newer heads there can be issues switching over the coil packs.After they reversed the packs,they bolted in the braket and it FIRED RIGHT UP!
I'm with the other on the whole "if the dots are lined up it can't be wrong",but that's why I have mechanic friends.
I will try to get him to come in and read my message and correct my mistakes as needed.

Why is this? I've never heard of anyone switching the coil packs from the passenger side to the drivers side, to prevent misfires. How does this help?

It doesn't matter if the coils are on the left or right.
What i meant by "backwards" is that when you put the coils back on you could have put them on backwards as in front to back and back to front. I don't remember seeing numbers on the ones i've messed with but i do remember that the coil that has the longest wire connecting it to the coils plup (the white one) goes towards the back (#8) on the passenger side and towards the front on the drivers side (#1).
