Inspired by Dart's championship winning Pro Stock designs, Dart Pro 1 aluminum cylinder heads cover a wide range of applications from street cars and trucks to all-out racing.

Heads designed for street performance and mild bracket racing offer excellent mid-range torque and power, and are excellent for heavier vehicles. Competition heads are ideal for maximum effort naturally aspirated, big boost forced induction, or nitrous applications.

Dart Marine Pro 1 cylinder heads feature an exclusive chromate surface finish to inhibit corrosion and extend the life of the head. They are also fitted with Inconel exhaust valves to withstand the extended running time and temperatures typical of marine usage.

Dart's as-cast ports flow more than many ported designs at a much more affordable price. But they also offer fully CNC-machined heads with every intake port, exhaust runner, valve bowl, and combustion chamber shaped by their 5-axis, computer controlled machining centers to produce compound curves and complex shapes that no human could duplicate with a hand grinder.

Available bare or fully assembled, long-wearing bronze valve guides, screw-in studs, multi-angle intake seats with hardened, radiused exhaust seats are standard on most heads. Assemblies typically include stainless steel valves, premium springs, locks, retainers, guide plates, and seals. Many Pro 1 heads include race-proven features such as rolled valve angles, improved spark plug location, extra-long intake valves, raised exhaust ports, and fast burn chambers.

They are offered an extensive variety of valve angles, intake port volumes and shapes, exhaust port locations, valve sizes, and chamber volumes. What is this?

Street Rods.When we last visited the evil Dr. FrankenRat, he had convinced us to bolt a blower on our Scoggin-Dickey-supplied H.

This simple step OK, it was expensive too! Rather than getting greedy by trying to better those numbers, we decided to tame our savage Rat and return to the land of the normally aspirated with a set of oval-port heads. Some may question the need to try a set of oval-port heads.

Our reasoning starts with the concept that Rat motors are finicky engines. Everybody thinks that these big engines need a monster head to feed those large-by-huge cylinders.

That may be true for 1,hp Pro Stock engines, but for a street-destinedwe think there may be some torque to be had by employing the services of an oval-port head. Our idea was to make more torque, even if we had to sacrifice a little peak horsepower to get there.

Why do this? Because despite the fact that everyone talks about horsepower, torque should get equal billing. Combine strong torque with good horsepower and you have an outstanding street combination that's fun to drive and delivers impressive numbers at the dragstrip.

This particular combination is intended as a mild pump-gas big-block with a goal of big torque and good throttle response. This could be used in a mild Chevelle or Camaro street combo, a pickup for towing although we'd suggest one step smaller on the camor even in a ski boat where low-end torque is king.

Rather than search for a set of production iron oval-port big-block heads, we went with a set of World Products Merlin oval-port heads. These heads feature an identical cc chamber but with big 2. Compared to the rectangle-port heads, this is a reduction of 41 cc's, which theory says should be worth low-speed torque and throttle response--all good things for a torquey street Rat.

The comparison would also be more equal since the compression ratio would remain the same at 8. In fact, this is one place where we could probably pick up perhaps 2 percent more power by increasing the static compression three-fourths of a ratio up to 9. The rectangle-port heads enjoyed the advantage of a degree back-cut on the intake valves before we bolted them on the engine--something we didn't do with the oval-port heads. To maintain a level playing field, we decided to install the same Crane valvesprings that we used on the rectangle-port heads since we had run into so many problems with valve float on the previous test with the rectangle-port heads.Due to shipper and supplier delays, your order may take longer to arrive.
