Single-Plane Manifold and CNC Ported Dash 3 Alloy Head Kit

This Torque-Power Single Plane manifold and CNC Ported Dash 3 Yella Terra heads are now available for the first time ever in Australia

This race CNC intake Port flowing 550HP at .600 valve lift with a 2.050 intake valve has a 186cc intake volume-runner with a 78cc ex Port and 61cc chamber.

All ports and chambers are CNC machined. The design of this High Flowing cylinder Head was accumulated by many countless hours spent by Micron and Torque-Power and by both flow bench and Dyno Testing.

    The exceptional flow obtained from Torque-Power’s new Single Plane and Micron Racing Engines designed CNC ported Alloy Dash 3 Heads, makes this manifold and head combo, perfect for the Holden 308, 330, 355, 383 engine displacement in Drag Cars, Street Cars, Boats and for the enthusiast.        

Heads are available bare or complete, but the idea of the manifold and CNC Ported head Combo was to help keep the cost down to achieve a large increase in Torque and HP, instead of a costly change to the later style EFI Holden head.

With this Top End Kit, a large percentage of cost savings are in not having to change ex pipes, cam, lifters, Rocker covers and Roller Rockers, as you would if you chose to change from Early Holden Heads to late Holden EFI style Heads.

Now there should be no problems for guys with early style Headed Holden engines to be able to make 500HP and over, as Torque-Power, Micron has done on there Proto Type 383 Engine shown below with Dyno test graph.
