bolt sizes?
Bought a couple of parts that came with no bolts looking for the sizes to replace them.
LS2 throttle body to manifold bolts
Coil pack bracket to valve cover bolts / studs
Front face of the cylinder head bolts ( where lifting mounts go )
Size pitch tread

Not sure myself but think the TB to manifold are m6 1 TP and m5 for the coil bracket, might have to take the parts to hardware store and start trying bolts. I can try and find them in my service manual (if it lists them) later on if nobody else knows!

I got the fuel rail to intake, TB blade (plate) bolts. I think the valve cover to coil brackets are the same pattern as the valve cover bolt just different length. I don't have the intake yet so I can't check TB yet. I didn't want to lug fully built heads to the store for the lift brackets.
The auto parts store people don't / didn't like me testing the bolts or they think im going to steal them.
TB plate 2 - M4-0.7 x ? ( 9MM - 13MM ) I had to cut it the stores was to Long.
Fuel rail to intake 4 - M6-1.0 x 15MM or 16MM
Oil pan( Smaller bolts ) 13? - M8-1.25 x 30MM

I might have to hit up a hardware / tool store. I know the top part of the covers were blasted clean.. then I sanded and painted might be some grit in there. I might just have to pack 1 head with me I'll figure it out its not impossible just thought someone would probably know off top of the head.

Valve cover to ignition coil brackets bolts were M6-1.0 x 20MM ( assuming GMs were 18.5 from what Paul posted but 20mms fit )
Engine lift brackets were M10-1.50 x 20MM
Comp cam / factory rocker arm bolts M8-1.25 x ?? ( I didn't need the length or size) just the Allen size. 7
@ sweet
The throttle body bolt will be 40MM+ then, the 30MM doesn't make it out the back of the TB holes.
