Just buy a bottle of Comp Cams 152 break-in lube from Summit or wherever you can find it. STP Oil Treatment also has "some" zinc in it as well.

However, if it's a tired worn out engine....who cares what oil you run in it? Zinc acts as a lubricant to keep your cam lobes from going flat. As far as "breaking of gunk and plugging your pick-up"....what? If the engine is at the point that your worried something might "come loose" and plug your pick-up, you're ready for a rebuild.

Just run whatever you want in it, it's not going to blow up or anything. At the worst you'll wipe a cam lobe and end up with a crappy running engine which you would have to rebuild anyway.
