cylinder heads

SB ford Hemi

Nick Arias Jr. Racing Components presents the world’s first Hemi® cylinder head for Ford 351 Windsor series blocks. The Arias SF-AH head kit will easily adapt to most 9.500” Windsor factory or aftermarket blocks, with a few minor modifications.

Arias Jr’s cast aluminum Ford Hemi head is poured from 356 T-6 alloy and features full water jacketing throughout. Offered are two choices of combustion chamber design; full round hemisphere or figure-8 shape with quench pads – both with central spark plug location for maximum combustion effectiveness.

This bolt-on or complete Crate Engine package is ready for the street rodder having the desire to stand out from the crowd; or the hardcore racer looking for the power and torque of a genuine Hemi® for their Windsor series foundation. Turn your run-of-the-mill Ford wedge into a hemispherical-chambered hero and put the spark plug holes running through the middle…where they belong!
