Need help with lq4 build!! I'm currently building a lq4 engine I'll be running 243 heads, long tube headers, 224r cam from Texas speed, no ac or power steering , truck intake, chromoly push rods, and custom tune. Looking to be right at 500 hp. Any one have any suggestions on upgrades that will get me there? I don't want to boost or use nitrous.

500 RWHP will take at least 235*/241* duration with well
Ported stock heads, 11.0:1 Comp minimum, 1 7/8 headers,
X Pipe with 2 1/2" dual exhaust minimum. Mamo Ported FAST
TRUCK Intake worth a bunch also (20+minimum)

What's the final compression going to be? In my opinion you should be no less than 480-90 at the crank....
Hot Rod Magazine too a 6.0 added gto headers, 40 series flowmasters, and a tune. Results was 410 horse and 440 ft lbs of torque. That was with the FACTORY cam and the with less performing 317 head.
A 208/212 duration cam would add 60 hp at the crank roughly over the factory cam (tested on a 5.7 ls1) .... A bigger 224 cam should add even more power than that. Good luck for your project.
