The "valve drop" on a 5.3 head is less then a 5.7 head i.e. a 5.3 head has less P to V then a 5.7 head, however, our 5.3 heads make SO much more power then the 5.7 that I would borrow our piston nothching tool and notch the pistons yourself, it's not hard.

Jason at TSP told me that my G5X3 114 would fit with the PRC 5.3 heads.
