Ls3 Cylinder Head Cam Intake Swap Comparison
|
Compared to the stock LS3 cylinder heads (left), the Mast castings have a much thicker 0.750-inch deck to prevent distortion in power adder applications. Optional are two extra stud bosses cast into the 12 o’ clock and 6 o’ clock positions around each cylinder, making them compatible with six-bolt aftermarket blocks. The valve cover rails have also been increased in height for extra rocker arm clearance. View Related Article
