LT4 HPFP & Injector Install Components

Aloha Corvette Family,

I am getting ready to kick off the install of my LT4 FP & Injectors on my LT1. I know a few of the fuel lines are one-time use due to the coating on the threads. I can't find what exact lines need to be replaced. Looking to get some help/guidance. I have posted below what I think needs to be replaced below.

12618338 ACDelco Fuel Injection Feed Lines

1
1267705 ACDelco Fuel Rail Components

12677003 ACDelco Fuel Rail Components

12672366 ACDelco Fuel Injector O-Ring and Seal Kit

Please let me know if these parts are needed for the swap.

Thanks In Advance
