ProComp/Speedmaster aluminum heads

That's not to bad for 5 year timing chain set. not bad at all.
Is that a true roller chain ? brand ?
Well my paperwork for my engine said true roller... I called the machine shop on it this morning because their numbers didn't seem to match up with anything I could find. You can see it says "sa" on there... I wrote it down it's out in the garage but he said pro something or other...
