These heads feature hardened valve seats, bronze valve guides, and threaded inserts in rocker stud and exhaust manifold holes, with hand blended valve pockets, 60 cc combustion chambers, and 5/8” thick deck surface (not for late model rail rockers). A 2.02” intake valve version is available; best suited for larger cubic inch engines and requires notched pistons for valve clearance.
