Product Description

MAST Motorsports LS7 Medium Bore Cylinder Heads

The engineering staff at MAST Motorsports has refined and reworked the powerful GM LS7 cylinder head design to work with the popular 416/418 LS3 based stroker engines and created their medium bore, LS7 265 cylinder head castings. This race-bred LS7 based cylinder head features higher flow intake and exhaust runners than any other aftermarket medium bore CNC ported LS7 style cylinder head. Utilizing their many years of hardcore racing cylinder head development, their 5 axis CNC precision porting equipment and high tech 3D solid modeling of the ports during their inception, these heads are far and away the best LS7 cylinder head currently available to the public. All you need is the short block that can handle the power they can deliver.

MAST LS7-MB Features:.

•  Utilizes the Gen IV LS7 valvetrain and intake manifold
•  Designed for any new Gen IV short-block with 4.000" or larger bore
•  2.165" intake valve and 1.600" exhaust valve
•  Minimum deck thickness of .75"
•  Fully CNC profiled combustion chamber

Each Mast Black Label cylinder head assembly includes:

• A fully CNC machined aluminum cylinder head
• PAC Racing .650" Lift Dual Valve Springs
• Mast lightweight stainless steel intake & exhaust valves
• Lightweight chromemoly steel retainers
