So far so good. I like your plan for it. (and the color too).
I am curious though, can you use the heads off a 6.0 on a 5.3 saflely? I ask because I thought the valves would hit the cylinder walls since the 5.3 has a smaller bore. Or am I confused? (and that is OFTEN )

yes, you can use up to a 2.00" valve safely on a smaller 4.8 or 5.3. Its only when you upgrade to the larger valves in like the L92 heads that there are clearance issues. You have to have at least a 4" bore to run those heads.
