BB Chevy Hemi

Nick Arias Jr. Racing Components reintroduces its Big Block Chevy Hemi® cylinder head for Mark IV series blocks. The Arias BB-AH head kit will easily adapt to most 10.200” and 11.200” deck G.M. factory or aftermarket blocks, with a few minor modifications.

Arias Jr’s cast aluminum Big Block Chevy Hemi head is poured from 356 T-6 alloy and features full water jacketing throughout. Extra thick decks boost combustion sealing and prevent coolant seepage. The notorious three-pushrod design has been reengineered to a more conventional setup, with one intake and one exhaust pushrod activating new needle bearing, roller tipped rockers.

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 Rat Motor foundation. This is the same cylinder head that dominated Drag cars & Boats and Tractor pullers for the last four decades, with today’s technology built in. Bolt on a piece of Hemi history today!
