Valve lash adjustment made it worse! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My truck's had a ticking sound that doesn't go away after it warms up. Today I adjusted the valve lash per the factory manual, thinking that might help. The ticking is now worse. I plan on checking the lash again, but I think I got it right. I figure at least now I know it's the valve train that's making the ticking. Is it possible that I set the lash correctly but because of some other problem, it sounds worse? Any help would be greatly appreciated! (BTW, it's a '72 C20 w/a 350).
