Following our win in the 2004 Popular Hot Roding Engine Masters Challenge with Jon Kaase using both CHI heads and 4500 Dominator Manifold, we set about looking for a suitable base for the development of our 2V & 4V Street Master Cylinder Heads.

In order to develop intake ports of equal calibre to our world renowned 3V cylinder heads, we wanted to work with a company that not only had the very latest computer aided development and testing equipment, but a proven track record with the famous Cleveland power plant.

CHI could look no further than Australia’s leading CNC porting experts, Kostecki Engine Centre In Perth Western Australia, to help with required research and development.

Kostecki Engine Centre is one of the few companies out side of North America to have a complete facility under one roof including 5 axis simultaneous CNC Port machining, Super flow 901 Computerized engine dyno, Superflow 1020 Computerized flow bench.

Most importantly though when looking for Research and Development results, we wanted a proven Cleveland powered performer from whom to draw experience. Team Kostecki campaign their own very successful Cleveland powered Mustang drag racing in the extremely competitive Super Stock G/gas Category. Their Mustang was the first in its class to run in the 8.30s and have set the national record at 8.44et at over 157mph with a single 750 carb and cast iron 4Vs making over 700 naturally aspirated horsepower from just 350ci !!!.

By utilizing KEC's extensive track experience as well as in house development facilities, CHI is proud to announce the all new Street Master 2V cylinder head.

At just 190cc in port volume the all new 2V flows a massive 307cfm at just .650”lift, with 300cfm at .600lift (figures taken from as cast head with a 2.100” valve), taking the 2V head to a new level of performance, never before available from a standard intake port location and size.
