4x4 cams will fit a 2wd head with spacers that fit on the nose of the cam (available from Burtons). You can't use 2wd cams in a 4x4 head unless you have the cams machined down a little.

What he said^^, the spacers go on the machined part of the cam and butt up against the bearing inner race on the inside of the head area, they are about 4.5mm thick from memory, stops the cam being pulled too far forwrds when tightening the pulley bolt up, so keeps lobes in position.
