I'm looking at LS6 heads and cams for my M6. I'm not really a car engine guy. I know my way around inline 4 and v twin motorcycle race engines, but thats another subject. Any recomendations for things to be done along with heads and cams such as heavier push rods or computer tune. I live in the sticks of NC and my resources are limited in this area, except for the dealer. Any advice will be appreciated.
