The Street Series kits have cylinder heads with 195cc intake runners, 64cc combustion chambers, 2.02/1.60in valves, and 1.450in dual valve springs rated to .550in of valve lift. The intake manifold is a LowRise dual plane. The kits are for flat tappet camshafts only.

The SuperStreet Series kits feature cylinder heads with 190cc intake runners, 64cc combustion chambers, 2.02/1.60in valves, and 1.450in dual valve springs rated to .580in of valve lift. They also include a MidRise dual plane intake manifold with integral nitrous bosses and four-corner water ports.

The Outlaw Series kits have the same cylinder heads as the SuperStreet kits but come with a MidRise Air air-gap dual plane intake.
