What am I forgetting for shortblock swap?
What am I forgetting for shortblock swap? --- New stuff --
Head bolt set
Head gaskets
Main pully bolt
Fully assembled short block w/ oil pump, cam already in
Lifters
Oil press sensor I broke
--- Old stuff ---
Take off heads (complete w/ dbl springs), pushrods, oil pan, front/rear covers, etc.
Do I need new gaskets for my headers?

Beats me; how about this stuff:
Thread locker
header gaskets
oil pickup tube
new lifters
hardened push rods
new oil/filter
Timing chain
timing chain cover seal and gasket
scotch pads for cleaning old head surface
tap and dies for cleaning out rocker bolt holes
radiator fluid (red not green)
oil pump seal 0-ring
flywheel, throw-out bearing, clutch
Engine hoist
rags
LS1 Edit
Small PC w/MS Windows
large knuckle bandaids!
book of choice curse words
endless bank account with checking overdraft
Your wife's credit cards
CHECK THE BACK OF THE NEW BLOCK - there is an oil galley passage hole that often does not have a plug in it; forget this and you have to remove the engine again or tranny....

Ok, they are not sure if the oil pump I ordered comes with a oil pump seal (oring?)
And I do NOT have LS1EDIT, I have a feeling my car will not idle without that either, and I don't have the $$ to buy it.

Did I memtion bigger fuel injectors
Full roller rockers

The stock 98 28lb/hr injectors won't work? Why do I need to replace my roller rockers, the 1.7 ratio is fine, will they break? I already have double valve springs and titanium retainers.
Also I have MSD spark plug wires that were on the car, they should be fine shouldn't they? And I plan to get new plugs.

Verdad Gallardo Do you think the car will idle with that big of a cam in there? The car has been tuned for a bigger unknown grind cam that was in there before I started tinkering with it, and the TB blade also has a hole drilled in it.
Is there a extra gasket / seal thing that I need to put between the oil pick up line and the oil pump? I thought there should be but there was none when i took my pickup line off.

Do you mean the O-ring that goes on the oil pick-up tube which is bolted (single bolt) to the oil pump. There should be a thick 0-ring on this tube - ussually blue or green in color.... without this you will almost zero oil pressure.

The car ran that way for quite some time from what I understand.
So to install a oil pump I need a seal for the back and the pickup line? I assume if I go down to the local dealer they will be able to order these for me?

It is the only GM part that my Chevy dealer carries in stock - oil pump o-rings!
'''remember to check the oil galley freeze plug on the back of the block before you install the engine/tranny; lots of folks here have forgotten that and end up with no oil pressure.... obviously, the 0-ring is critical too...

Not sure on that one. You should post a separate question with the tittle, "LQ4 iron block swap - alternator bracket"
You might also post a separate question about the fuel injectors on the "Tuning" section of this board.
I know long-tube headers make your O2 sensors over-compensate and run the motor rich. Since you now have a bigger motor that requires more fuel your factory tune and injectors may be close. I'm sure those who know will tell you to get the full performance from a 408ci motor you need to get bigger injectors AND a tune....
Take their advice with a grain of salt...
What I do recommend is that you run a computer analysis program after the install. These are cheap ($80). This will tell you whether your motor is rich or lean. Remember a rich motor will not casue damage -- a very lean motor will cause detonation and will cause lots of internal damage....
One other MAJOR item. When you remove your coil packs mark them with tape. Driver's side front, passanfger's side front.
If you don't your ignition will likely be totally screwed up!!!!

I didn't have to remove the coil packs from the valve covers.
