I can't find it in the service manual; I want to know the installed valve height recommended by Nissan for the S13 SR20DET. I have way too much clearance between my rocker arms and the cams. (I need 3.4mm shims to make the clearance correct... which isn't available. 3.2mm for the shims and only 3.0mm for the guides are available). I think the machinist ground too much off the valve stem ends... he went off of the installed height on a 91 SE-R motor.
