hey guys! i have tried to make a valve lash adjustment on my 1955 ford truck. The problem is that my rocker is still noisy for some reason. The truck manual says .16 on intake and .18 exhaust which is right but i have adjusted them at .19 both like shop manual says. Which one is right I can't figure it out. email me at my grandaughters email address Caleighhhx46@aim.com. Please help! Thank you.
