I haven't used those particular rods but two things I'd emphasize...
1. Those are a better material and a better bolt and design. But they are for pressed pin piston designs. make sure your pistons are pressed pin.
2. Historically I have found the rods Source sells are cycled (the caps torqued, loosened, and retorqued a couple times in a rod vise) the big ends tend to distort. Out of 6 sets I've used over the years (different lengths and bore sizes) they have always distorted to some extent. In two cases I had to pay to have the big ends resized properly. As with all machined products - the parts should be carefully checked by a qualified machinist before use. This is not a complaint - just a reality and it's a similar issue with any aftermarket part for any engine.
