In general I'm not a proponent of aluminum radiators. I had a mighty expensive Made in USA one from Fluidyne that I installed on a '66 Mustang,
thinking it would cool better than the old copper brass unit. My new radiator was in the car about 3 days before I had a hand-built copper brass one back in the car. The aluminum unit took longer to heat up but it ran 20 degrees hotter. So much for "3 rows of staggered tube" BS being better. I'll take the "inefficiency" of 4 inline rows and the lower operating temp of the copper brass.

Might be different with a flathead engine, but my 10.5:1 Windsor didn't like it.
