The ad says those 915's need a rebuild, so imho they get you no closer to your goal than your 452's, especially since this pistons gotta go either way.
I'd replace the pistons with one of the above KB's and either rebuild your 452's or go aluminum depending on your performance goals. I'm using the 440 source heads box stock. Checked out OK by my machinist and the springs work with my lunati cam. $999 delivered and with a them, my 451 really hauls the mail.
