Just cut the line back 1/4" or so to expose a new area of undamaged tubing. There's usually enough slack to do that. BTW- - - -the link for the replacement oil line you provided is not the correct one- - - -that's a 1/8" diameter EXTERNAL line that goes around the back of the cylinder head and joins the oil pressure line, and bypasses the internal engine plumbing by making use of the 1/8" pipe plug at the center of the head. It has nothing to do with replacing the line to the oil connector at the rocker shafts.
