Cam breakin Procedure

Sorry, I forgot the assembly changes that you should make...lol. The lifter rotation needs to be checked. In my case, I either use a flex hone, or a ball burnisher to properly size the lifter holes. Then I install the cam with no lube, and the lifters w/WD40 on the sides. Mark each lifter and the bore with a black permanent marker, then rotate the cam in the block with the timing set installed. You should see the balckmarks seperate on every lifter, about 8-10° every time the lifter goes up and down on the lobe. If it doesnt, you can mix and match or if you must, hone or remove the burrs that might be stopping it. Then, when the heads are assembled, if you run a double spring, leave the inners out. Replace them after the cam has been broken in and the break in oil/filter dropped.
Sorry I left that out before...lol.
