Head and Cam choice for 416 LS3
I am trying to figure out the best head and cam choice for the items I have purchased thus far. I will list the items and I want suggestions on the best combos for my setup. I'm not trying to break the bank but I also want a reliable and sound setup. Quality first and foremost. I am trying to achieve about 525 rwhp. Many thanks for any suggestions.
