MERLIN X 16°

BIG BLOCK CHEVROLET

ALUMINUM CYLINDER HEADS

This all-new design from World's engineering team combines flow characteristics common to expensive race-only heads with exotic splayed valve setups while allowing use of popular Chevy Mark IV style valve train components, as well as  standard intake systems. This has been accomplished through “rolling” the head to a 16° valve angle, designing highly efficient intake and exhaust ports, and using a special 80cc combustion chamber. You'll probably need to get a set of pistons that take advantage of the chamber design, but other than that you can use most everything from a standard Big Block Chevy and when you add up the performance potential versus total cash outlay, it's clearly the “hot set up” for Sportsman racers. Available bare, or fully assembled with a choice of valve/valve spring packages.
