Yes, Heimerdinger's turrets damage goes up when he gets Magic Pen... it has been like this for a long time. I have tested it watching turret damage go up on the same mobs as soon as I bought Sorceror's boots.

Also, unlike adding AP, turrets get the benefit of his added mpen as soon as he gets it, and don't need to be replaced to start doing more damage.
