I am wondering what would be the best combo for a new motor. Have built a short block with 6" rotating assembly. 13.5 compression with small chamber heads. I have a set of 461's with small valves, and a set of 487's with small valves. Which would you choose & why?

Use the 461's because they move more air , and they have a 62cc chamber in stock form , instead of the 75cc chamber that the 3973487 heads have .
