ARod and Bonds are different from McGuire, Canseco, Palmiero and Sosa, as they would be Hall of Famers without the juice. Clemons as well. But ARod and Bonds are going to be 1 and 2 all time in homers, and it's not fair to all the guys who didn't use.
Fred McGriff's 493 homers would be Hall of Fame material if everyone had been clean, as there would be about 10 less 500 homer guys.
Ken Griffey Jr. is realistically only the 4th guy to hit 600 homers, as Bonds and Sosa would have never reached that without performance enhancers.
Hank Aaron is still the true homerun champ career-wise and Roger Maris is the real single season leader !
