Any input on what shaft mounted rockers to use?

I'm willing to bet a 6 pack of your favorite brew, that with similar valve spring pressures, a 289 or 302 with the spark plugs out & with a flat tappet cam & roller rocker arms will be harder to turn over by hand than a 427 engine with the plugs out & with a similar non-roller camshaft. The difference won't be as much as with a small block with the stamped rocker arms, but the BB will still turn over easier.
