Clicking in the engine - Where would you look? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an Olds 455 in my '64 and it has developed a clicking/clacking when I accelerate and rpms are above 2000. Engine oil was metal free as was the Wix filter media, thankfully. I'm in the process of readjusting the roller tip rockers. I've retightened the exhaust manifold bolts and they were good. I'll be checking the flexplate bolts, too.

What else should I be looking into? Can roller tip rockers be loud?
