Can someone take a look at these and tell me if I am doing these right. I used a cartridge roll on a hand held die grinder to get the rough spots out and then used sand paper to smooth things out and then jeweler's rouge to polish. All grinding and polishing was done vertically from big end to small end. I hope I did these right!!

here's your images, looks fine to me (removing the casting lines from the beam is the most important part)

be sure to have them balanced with your crank, and pistons

 

ditto!

 

better yet, have them shotpeened.
then balanced.

Thanks for posting the pictures for me Texan!

 

Idiot question... what would the benefits of doing this be?

 

Removing the casting lines and other sharp edges removes places where stress fractures can start. Generally stress fractures start at a metallurgical weak point such as a sharp, rough edge.
