I have for sale a like new set of Comp Cams Hi-Tech Stainless Roller Rocker Arms™ for a 460/514, 1.8 ratio. They will not work with my new cam profile.
They were really expensive, $360.00...Just put 'em in last summer too damnit...
Super Ford tested them and they gave 35 additional HP to a 514 Crate motor (over stock 1.7's) with no other mods! That's pretty good. The 1.8 ratio really gives a lot more lift without changing the cam... resulting in big HP.

Hi-Tech Stainless Roller Rocker Arms™
Hi-Tech stainless steel rockers are the toughest rockers in racing. That’s why they’re the choice of professional racers. We use 15-5 PH stainless steel—a premium alloy that’s high in Nickel and Chromium. This superior material gives Hi-Tech rockers outstanding yield strength and exceptional fatigue resistance. Our stainless rocker arms are extra rigid (tested at 52,000 pounds/inch!) to resist power-robbing deflection.
Hi-Tech rockers are engineered to minimize reciprocating weight—that means more rpm and longer valve train life. They’re designed for race-winning durability, too. Our engineers specified extra large trunions and more needle bearings to spread out the load and reduce wear. Hi-Tech stainless steel rockers are available in ratios to suit every camshaft profile. Our stainless rockers are rebuildable, too.
They’re an investment that pays big dividends in performance and dependability.
Rebuildable!
Unlike aluminum rockers, this heavy duty rocker can be rebuilt. We will disassemble and inspect it, then replace the roller tip, axle, trunion and bearings to make your rockers like new.
