Yeah, there are some good results with the factory heads (LS6 243/799 castings). Its 'SAE' rated at 395hp/400 ft lbs. With headers, cam, etc, they are an easy 475-500hp on stock heads, and about 550hp with worked heads.

I think I will keep the stock heads for now but I want a cam, there's a few that work well for the heavy TBSS trucks.
