one thing i did forget to mention is the coolant crossover tube has to be bent down a little cause it hits the bottom of the throttle body, check the pic in post 33 it shows how close to the vally cover the throttle body is i hadnt installed the crossover tube yet in that pic

Nice. I'm doing a similar swap. I'm pulling the 4.8 and putting in a 6.0 with LS3 heads, L92 truck intake, and an "03" Z06 cam.

with a small cam like an ls6 cam you should be able to mill .030 to bring up compression, if i remember an 03 and later ls6 is a 204 219 right? i would check ptc clearance but i think you would have more then enough room and with 65cc chambers you would be somwhere around 10:1 if your using an lq4 and 10.5:1 if using an lq9

also just a suggestion i would stay with the solid valve l92s they are cheaper and stronger then popin for the more expensive ls3s

I already have the LS3 valves installed. As for milling the heads, I already bolted them on. I'm keeping it quiet with the stock exhaust for Grouse hunting. I do tow my Sea Doo quite often in the summer with truck. The extra power should surprise a few people. What kind of power do you think you'll make?

Question

Do the stock LQ4 iron head exhaust manifolds fit the L92 heads?
