This is exactly what I'm hearing from the builders that have extensive experience with boosing LT motors. Better to go with the LT4 secondary fuel system parts unless you want to get absolutely nuts like 800+. And even then the LT4 block is supposed to be good for 1000 hp. It may be more economical to buy a GM LT4 crate engine rather than building a forged LT1. GM already built the best high pressure fuel system when they set-up the LT4. I must admit that I expect another GM engine upgrade beyond the LT4 whenever the Zora Corvette is finally released. This is going to be the stuff to have whenever the public can get our hands on it.
