6.0 Lq9, small 224 cathedral cam with square port heads? Anyone running a 6.0 lq9 with a small cam like around a 224 for cathedral heads but with square ports?
Or will the lq9 for a fact be better with stock 317 heads?
Really wanting some real world experience knowledge if possible.

Your gonna get several different answers, and lots of opinions. It’s a very debatable topic that really has no right or wrong answer. I’ll give you a real world experience example that I’m working on right now. I’m starting a build right now in my shop. Just got everything back from machine shop, and everything is together and ready to start mock-up. It’s a .030” over 6 liter block (LQ4) that will have GMPP LS3 CNC’d heads on it. Going in a 99’ Silverado 4wd ext cab, which is a heavy truck. We are looking for torque, and I had Tony Mamo spec the camshaft. It’s a 219/231 Comp hydraulic roller. Engine will never see 6500 rpm. This is not the first square port build I’ve done for torque, and I can make it work with the right parts.
As Mavn said in the previous post, there are many threads about this subject.

I see posts with cathedral heads and a cathedral 224 specd cam.
Or square port heads and square port specd cam.
I didn’t see a 224 specd cathedral cam with square port heads.
I only found one that talked about a small square port cam with square heads.
I’ll search again, I’d ask on fb but too bs there vs here

Get a hold of a vendor like Steven from Cam Motion. He is very knowledgeable. I talked with him for a bit about this subject on Friday. He explained a lot about it for sure.
