LS3 Medium Bore | Factory Mast | CNC Ported | Cylinder Head - Single Bare
We took the Factory Mast LS3- and CNC ported it for even more improvement. Our Factory Mast Cylinder Head starts out with our "as cast" port which we now offer a CNC port for more airflow. This allows for an additional option and price point over our As Cast Port version and our Premium Black Label LS3.
We launched our Factory Mast product line to deliver an economical product line for our customers.
You have come to love the "Black Label" Cylinder heads, but now you can get the same quality at a lower price withoutSACRIFICINGperformance.
Manufactured using permanent mold technology, this casting is simply an amazing surface finish and quality.
Mast refuses to compromise on materials and methods that may jeopardize longevity, performance, and quality. When buying Mast Cylinder heads, you are getting the highest level of quality and performance on the market.
