EDIT: I've decided not to use these heads on my tow pig for the simple fact that IAT's frequently reach 130+ where I live, and it gets thrashed really hard while towing my camper. I'd rather keep the compression down and not be so octane-dependent.
And holy crap, it appears the internet hasn't changed at all since I stopped frequenting forums.
----------------
For starters, I have a 2006 1500HD that needs to tow a lot better than it does(currently completely stock with 3.73's and 33's). My plan as of right now is to install a pair of Greg Good ported 706 heads, a Truck Norris cam, TBSS intake, 1 3/4" headers, and possibly 4.56 gears. I'll decide on the gears after I get a feel for the torque curve after all the engine mods.
My concern is being able to run 93 octane with that much dynamic compression on an engine that will be towing a camper through mountains and receiving a healthy flogging on a regular basis. Am I over-thinking this, or will 10.6:1 SC be totally safe with a cam that small on a tow pig?
