Early V8 Holden enthusiasts get ready.
The ultimate HQ-WB Mid-Port Alloy cylinder head is here.

The latest release from Torque Power - the TP182cc/223cc Mid-Port Alloy Cylinder Head - has been remastered with more benefits for horsepower and reliability than any other early V8 Holden head for sale on the market today.

BREAK THROUGH
With the new TP182cc/223cc & the flow rate that is achievable as cast, Holden enthusiasts will no longer need to purchase VN - EFi style heads to achieve upto 600+ HP. This is a huge benefit, and not to mention, a massive cost saving - when undertaking a VN - EFi head conversion/upgrade; exhaust pipes, cam, lifters, pistons, rocker covers & manifold need to all be purchased again to accommodate an VN - EFi head design.

NOT ANY MORE.

Spec 1 - Bare Head
'As Cast' ports & chambers

Spec 2 - Bare Head
'As Cast' ports & CNC machined chambers

Spec 3 - Fully Loaded
Fully CNC ported or 'As Cast' with CNC chambers (also available bare)

- New chamber design for better burning
- One piece rocker rail for valve train stability
- Large 5/8" or 16mm drain back holes, which is a massive assistance with oil return
- Thicker deck of 0.625"
- Big 9/16" (14mm) push rod holes to suit 3/8" push rods
- Bare as cast heads TP182cc are supplied with CNC chambers
- TP182cc heads can be purchased loaded as well
- TP182cc heads are available in CNC ported versions
- Heads available in 4 and 6 stud designs
- One piece water jacket
- New spark plug location
- Fully CNC machined outer-casting

One of the most noticeable improvement in the TP182cc over other aftermarket heads available today is the design provision to have two extra head studs per cylinder. This will provide racers with the extra clamping force required on the head gasket when high combustion pressures that are obtained when turbos, superchargers and nitrous are used.

Another key feature are that the valve angle is still 5° providing OAHF (optimum average head flow).

The As Cast head has 2.055 intake and 1.600" exhaust ports. The fully CNC ported head has 2.080" intake and 1.600" exhaust ports.

 
Available Configurations

The TP182cc is available bare, either As Cast (ports & chambers) or with As Cast ports and CNC machined chambers. The TP182cc cylinder head is also available with the ultimate CNC ported package - machined chambers, intake and exhaust ports. All configurations are available with or without seats cut.

Heads can also be purchased fully loaded in all above configurations, and also in both Top End and Cam & Manifold Kits with several different spring packages.

TP182cc & TP223cc DESIGN FEATURES

NEW VALLEY SPACER DESIGN SUPPLIED WITH HEADS.

Due to the higher port design of the remastered TP182cc head, standard engine blocks require additional height to seal the manifold.

Our new heads come with our Custom Valley Spacer Set supplied. This machined set of billet alloy ribs align perfectly to the top of the engine block, compensating for the gap created by the cylinder heads, enabling a precision seal of the manifold to the block (as seen in pics 1-4).

Want to achieve a seamless result? When using the Big Paw or Little Paw block, no valley spacer is required to align & seal the block, heads & manifold together.

ACHIEVE MAXIMUM OUTPUT.

The TP001 Hi-Rise Single Plane & TP020 Dual Plane Hi-Rise intake manifolds for early Holden V8's are designed to reach maximum output of the TP182cc cylinder head. Both heads and either manifold can be purchased together as a Top End Package, as seen together in pics 3 & 4 to right.
