Lq4 with 706 heads

[05lq4]

Question: Is there anything special i need to worry about when putting 5.3l heads on my 6.0? Can i use 6.0 head gasket? Do i need to match rocker arm assembly? Or are they interchangeable? Any unforseen pains in the @$$ i should know about?? 

Im about to do  my head gaskets and am thinking about swapping my 317s for some 5.3 heads if i can find a good deal. I dont want a race truck. Will never do forced air or anything like that. Might do a cam a few years down the road...

Do i use 6.0 or 5.3 head bolts? Google and YouTube arent as much help as i imagined in these details.

I'm not sure how much help I can be here.  Any particular reasons you are looking for 5.3 heads?  Higher compression?  I would imagine you still need the 6.0 head gasket due to the 4 inch bore.

4.8, 5.3 and 6.0 all use the same head bolts.

Awesome! Thanks for the feedback. Yes im hunting higher compression. From what ive read it seems to be a simple and cheap upgrade for lowend power. Truck started eating a minor amount of coolant so i figured since im Gunna have it tore apart might as well have a lil more get up n go when its back together.
