PRO 1 aluminum big-block cylinder heads deliver "out-of-the-box" airflow that beats the competition - at an unbeatable price! Specifically designed for performance marine engines, PRO 1 heads make Pro Stock airflow technology affordable for every big-block owner.

Inspired by our championship-winning Pro Stock designs, the PRO 1's race-proven features include rolled valve angles, improved spark plug location, extra-long intake valves, raised exhaust ports, and fast-burn chambers - yet the PRO 1 can be used with off-the-shelf pistons, valve train components, and intake manifolds. You get more power for your money with PRO 1.

Using advanced manufacturing techniques, we cast the PRO 1's ports with incredible accuracy. This precision casting technology duplicates the contours that were previously available only in hand-ported cylinder heads.
PRO 1 big-block heads are available with a choice of three different intake port sizes - 310cc, 325cc, and 345cc so you can match the runners to your engines displacement and RPM range perfectly.

• Premium alloy: KE aluminum heads are cast from virgin 356-T6 aerospace aluminum alloy for superior strength and integrity.
• Bolt on compatibility: 2° rolled valve angle and standard spacing. Accommodates all stock accessories
• Heart-shaped 119cc chambers improve combustion efficiency.
• Raised spark plug location improves flame travel for a quicker, more complete burn - producing more power.
• Multi-angle intake seats and radiused exhaust seats dramatically increase airflow.
• Hardened exhaust seats are compatible with unleaded gasoline.
• Exhaust ports raised .300" to improve flow (requires 1" longer head bolts next to exhaust ports).
• Spark plug holes are machined and gasketed for 3/4" reach plugs.
• Manganese bronze valve guides extend cylinder head life and reduce stem wear.
• As-cast heads are bowl blended on 5-axis CNC machining centers.
• Head Assemblies include heavy-duty marine stainless steel intake valves and inconel exhaust valves.
• NEW Dielectric hardcoat surface treatment protects aluminum cylinder heads against corrosion from saltwater environments.
Combining excellent intake flow numbers with a great exhaust port, Keith Eickert's new Signature Series PRO 1 head produces an amazing 79% exhaust/intake flow ratio...this head is a great choice!
