Intake Manifold Information

The Qualifier series line of Manifolds is one of our most popular high performance street manifolds. Procomp Low Rise intake manifolds feature a single-plane design that can give you mid range horsepower without affecting the low-range. What Procomp did was increase the plenum volume and alter the short-side radius of the runners, to give the air/fuel charge a straight shot at the intake valves. That straight shot produces a potent power build from 1,500 to 6,500 rpm.

Suits: 253 / 308 / 304 Bottom end with 304 (EFI) Cylinder Heads
Note: Can be drilled to suit EF Injectors (Extra cost).

Intake Manifold Gasket Information

Speedmaster intake manifold gaskets have Printoseal construction, which puts beads of special elastomers around the ports for extra sealing power. They also feature a non-metallic, rubber-fiber base material that resists gasoline and alcohol, while allowing engine builders to precision-trim around the intake ports.

Cylinder Heads Suggested Parts

Head Gaskets
Because our VN head is designed as a performance replacement for the factory head, you can use any OEM style head gaskets.

We prefer our Speedmaster MLS head gasket PCE348.1027. With all stainless construction, you won’t find a better gasket anywhere!

If you prefer Fel-Pro, use Fel-Pro # 1059 headgaskets.

Spark Plugs
Our Holden 304-308 cylinder heads require the use of a 14m. thread, 5/8” hex, .750” reach spark plug. Below you will find a list of some plugs that fit and work with our heads:

NGK - BCPR6ES, R5671A-7, R5671A-8
Autolite - 3923, 3924, AR3933, AR3934
Champion - RC12YC, RC10YC4, RC9YC3

Remember that you need a COLDER plug when you make more power, ie. N2O, Turbo and Supercharging!

Head Bolts / Studs
The head bolts / studs required are the same as factory Holden heads.

Speedmaster offers a 190,000 psi. head stud kit to suit our VN perfectly! the part number is PCE279.1020

ARP also offers both head bolts and head stud kits. Their head bolt kit is #205-3601 and the head stud kit is # 205-4601. Be careful to torque the heads following the OEM sequence in 3 steps to a final torque setting of 65lbs. using high pressure molly lube under the nuts and on the exposed threads of the studs.

Intake / Exhaust Gaskets
The Speedmaster heads are designed around using factory replacement gaskets.

We offer two different styles of intake gaskets. The Speedmaster PCE349.1017 is a paper style gasket for people looking for the lowest cost option, or head porters that are want a plain gasket they can trim to fit enlarged ports. We also have a premium Printed Sealer type gasket, Speedmaster PCE349.1016.
