I agree with you on the stupidity knows no age thing .Im in my 30's and this man is in his mid 60's ,but i had to give him a crash course about how rocker tips "scrub" on valve stem tips ,and i consider myself a novice with Mopars .As a former Chevy and Ford racer myself ,this is the first Mopar i have messed with or even owned in my life.I figured with over 40 years of expierence in Automotive Machine he would have worked on a SBM head...
