Searched everywhere, cant find it. Anyone out there know what the piston to valve clearance on a 1999 B20Z is? I'm going to mill the head and swap to a copper head gasket, so I want to try to figure out how much I can mill, and what size the head gasket should be.

 

are you using the stock b20 cams?
