John,
IMHO .......... no problem. Twenty minute runs are standard on race engines
I (& others also) build. Twenty minutes @ 2000 RPM, check oil press, temp,
carb settings etc. Shut down, change oil & filter, make adjustments, check
for obvious problems. Repeat run, & second oil change. Repeat third time,
re-torque head, drain oil, install in car.
I left out a few details, but I guess the point is, it shouldn't hurt your
engine to warm it up. I feel its better than leaving the condensation in the
oil to create acid or sludge over the winter.
Hope this helped.
