Which Roller Rockers?

OK im looking to buy a set of roller rockers for my 1987 corvette 350 (aluminum head option). Im between two sets from the Summit Magazine. Here they are:

Summit: SUM-G6920B Chevrolet: 262-400, 1.6 ratio, 3/8 in. stud, aluminum, anodized blue finish, roller rocker arm set


Comp: CCA-1418-16 Chevrolet: 1987-up 305, 350 with self aligning, 3/8 in. stud, 1.6 ratio, chromemoly, roller tip rockers

Both are 1.6 ratio but the Summit ones are aluminum which is making me think is that enough to go with the lighter Summit roller rockers over the big name Comp. company which are all steel. Basically I want to know which are going to be most beneficial to my engine as far as Horsepower and Torque. Both are about 190$. I have an aluminum edlebrock torker manifold, plus aluminum heads so the whole top of the engine is aluminum, saving weight is only beneficial to making more horsepower, better et's etc. but what should i do with this?

Any weight you can take out of the valve train is always advantages. RPM's quicker. Comp does makes a set of Hi Tech Stainless Steel rockers that are lighter then the aluminum. A bit more expensive however.

I'm running the Crane aluminum on my sbc and like them fine.
Its possible the summits are made way west of LA, if ya know what I mean.
