Does anyone have any idea on how many pounds is needed for crankshaft bearing and for the cylinder head? i'm replacing my piston rings.

 

Have you downloaded the Rave manual? It lists all torque specs and repair procedures. For something like piston rings, it would be invaluable to have.

Never jump into an engine without a manual, that is just asking for problems.
Just curious, why are you replacing the rings, they rarely ever fail in this engine.
There is a link to the Rave CD in my signature section.
