There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

No roller rockers or lifters are made for the 216-235-261 engine family. There were some "Baker hi-lift" rocker arms made in the '50s, but good luck finding a set. But by the time you got to the RPM range where they'd make a differance, pieces of the motor would be flying through the fenders. The '40s era chevy engines will grenade if revved past 3500 RPM on a regular basis.
The 216 is a "splash-oiled" system that uses dippers and nozzles to spray oil at the big end of the conn rods, as there are no oil passages drilled in the crank. This combined with only 4 main bearings, is not the hot ticket for power.

I have one intake rocker that's been making noise and tonight I checked it and its got a thump to it when I touch it running and is rough moving with engine off. I picked up a set of Fenton high lifts a couple of years ago, and figure I might as well use them when I overhaul the rocker assembly tomorrow. Not for racing, but it is just a bit hilly here in North Georgia...
