I have a 6.0 lq4 engine and came across a set of Ls3 heads with the truck intake for a great price. I also just bought a set of LS6 799 heads for it. I dont know which set to install now.....The ls6 heads are low mileage but the LS3 heads have about 190000 miles on them. I can get a new LS3 intake for 200$ or use the truck intake. Its a daily driver and wanted the LS6 heads for increased compression and torque. The LS3 make a lot more horsepower though...I can sell the LS3 heads easily and buy a nice intake for the LS6 heads to dress up the engine and get a bit more power. What should I do??
