6.0 LQ4 Build Hey all, I’m getting an LQ4, possibly a LQ9 this weekend. It’s going in a 02 yukon
What should be the best build to get 400-450 RWHP! And N/A as well.
milled 317’s? I wanna go 54-469-11 cam, what else should I do head wise? Anything is welcome!!!

What he said about the heads. For a bigger cam especially, you need the higher compression. The stock LQ4 most particularly won't respond well as-is. The LQ9 probably doesn't even have enough compression in stock trim (317 heads).
That's A SHIPLOAD of cam. Also not ideal for any cathedral-port heads; it's set up for square-ports. Not really the right thing, unless you're planning on LOTS of nitrous.
For pure N/A, if you're willing to bite off on THAT MUCH cam, look at one more like about this, along with the later-model heads. https://www.texas-speed.com/p-1149-t...-camshaft.aspx
