3rd Pic

 

If those are aluminum, I would identify them as "toys". I don't think an engine would run for 10 seconds with that little aluminum between the trunnion and the tip, without breaking enough of them to stop running.

They look like steel ones, but I don't recognize the brand.

Here's what good quality steel ones should look like.

look more like steel to me too, comp makes the only rockers i'll use.

 

Theyre Comp Cams Pro Magnum rockers. Theyre made of steel, and are stonger, and lighter than ANY other aluminum rockers on the market.

 

They're not Comp's.... the link I posted is to those, and the ones in the pic are definitely not those. They're not the better Comp ones either (the "Hi-Tech" line); I have a set of those on one of my motors too, which aren't what's in the pic.

I don't know who else makes steel roller rockers, but someone obviously does.

 

The CC pro mag rocker is 216 grams,
so nope sorry, they are much heavier than
any of the aluminum rockers.

The ones in the picture don't match, but look a lot
like the pro mags or Crowers.
