I’m running that same set up.

The HPFP is a straight swap. I didn’t have to shim anything. Just make sure the lobe under the pump is down (by rotating the engine) before you bolt down the new pump. Lots of instruction videos online. As mentioned, change out the HP fuel lines. Injectors were also an easy straight swap. I made 714whp SAE on e84 in Denver on stock pulleys.
