Review on 🔩 AMC 290-401/Pontiac V8 Flat 1 Piece Guide Plate Set with 5/16" Pushrod and 7/16" Stud by Stephen Thomas

THESE INSTRUCTIONS WILL BE NEEDED IF USING HIGH RATIO ROCKER ARMS LIKE ME. CHECK FIT CAREFULLY BEFORE INSTALLATION. YOU MAY HAVE TO REMOVE SOME CASTINGS TO RETAIN CLEARANCE. WHEN USING HIGH RATIO ROCKERS, IT MAY BE NECESSARY TO EXTEND THE PUSHER HOLES IN THE HEAD TO PREVENT PUSHER ENGAGEMENT WITH THE CAM FULLY RAISED. BOLT AND HOLES MUST BE CLEAN AND OIL FREE, PUT A DROPPING LOCKTITE ON THE THREADS. AS THERE IS A SMALL GAP IN THE STUD HOLES, USE A SCREWDRIVER OR OTHER TOOL TO HOLD THE PLATE ON THE STUD WHEN TIGHTENING.
