ROLLER ROCKERS www.TAPERFORMANCE.com TA Performance Products, Inc. 480-922-6807 Order and Tech Line 47 Roller Rocker Arm Assemblies We at TA Performance pride ourselves in providing the best parts for Buick engines, one key item from our product line is our proprietary designed Roller Rockers. TA Roller Rockers feature the best materials, strongest hardware, an internal girdle feature and superior fit which make these full roller design rockers the best on the market. All of our rockers incorporate these key features: 2024-T4 extruded aluminum alloy with a tensile strength equivalent to 75,000 lbs, far stronger than 6061-T6 material used on other rockers that equal only 48,000 lbs. tensile strength. 7/16 treated and hardened as opposed to breakage prone 3/8 adjusters found on other rockers. Torrington bearings on the shaft reduce friction and provide increased durability over bushed rockers. 8620 heat treatment and copper plating method that also incorporates exact tolerance bolt holes which results in the strongest shaft on the market. Our TA 1323 rocker stud kit is included with all rockers for the most secure installation to the cylinder head. TA Performance rockers are red anodized with gold anodized spacers, and each rocker is stamped with the TA logo on the top. All rocker sets are fully assembled and ready to bolt on. STAGE 1 2 rockers fit all factory 400-430-455 Standard, Stage 1 and Stage 2 cylinder heads, as well as TA Performance Stage 1 and Stage 2 series aluminum heads. These rockers are .990 wide which is .090 wider than other rockers on the market. The wider rocker allows us to incorporate an internal girdle in the center, between the two shaft bearings, this increases the strength of the arm and allows for additional clearancing of the rocker underside to clear larger O.D. springs. STAGE 3 rockers include the same features as our Stage 1 2, rockers but are larger in width in order to incorporate the necessary offset for the additional valve spacing used on Stage 3 heads. STAGE 4 rockers take it one step further and incorporate a wider intake rocker to accommodate a .200 adjuster screw, offset due to the repositioned intake pushrod incorporated on Stage 4 heads. 350 rockers include all features of our Stage 1 2 rockers and will fit `68-`81 350 engines Part Nos.

TA 1312 TA 1312 Shown TA 1310, 1311, 1313, 1314A B, 1315A B similar TA 1314C D, 1315C D similar to TA V1308 shown on next page If using 1.500 or larger diameter springs the rockers will need additional clearancing. This is a very CRITICAL process! DO NOT grind the rockers to clear, they must be machined as minimal as possible. We encourage your machinist to contact us for details on performing this modification, or we can perform the additional clearancing. If done incorrectly, you WILL break a rocker! !!!!!!
