Default Engine bolt sizes

I've searched here and ls1howto and google and yahoo.
I've only got a couple sizes but I need pretty much all of them.
I'll put them all on a spread sheet and post it up here so anyone rebuilding can make sure they have the right sizes.

If someone has already done this please tell me.
I filled a couple in so you can see what i'm looking for exactly the number in brackets is the number of bolts for said component.

Here's the list:

oil pan
windage tray (nuts)
pick-up tube
oil pump
camshaft retaining plate - m8x1.25x20mm (4)
camshaft sprocket bolts - m8x1.25x24.4mm (3)
rear cover
timing cover
waterpump - m8x1.25x82.6mm (6)
flywheel
valley cover
valve cover
intake manifold - m6x1.0x21.8mm (10)
throttle body to intake manifold - m6x1.0x30mm (3)
exhaust manifold
coil bracket and coil
