500hp 6.0?

many people go with them since they offer the largest combustion chamber of factory heads

Awesome! Then I'll scratch heads off the list & use the stockers. I thought these old iron heads were junk. My engine has over 186k on it & its going to get a rebuild soon.

317s is what most people run with FI thats the aluminum 6.0 head

I drive this truck all most everyday and I off-road it everynow and then. I checked ebay last night and the only set of LS3 heads I found were right at $1300.00. Is that a good price?

200 more and you can some ported and polished ;) are those fully assembled ?

Yeah that was a fully assembled set.

get aluminum heads, you can run more compression before you get detonation with aluminum
