Race City Race Parts AirFlo Restrictor Plate Cylinder Heads have won a lot of races.

The Restrictor Plate Cylinder Heads have smaller runners for better velocity.

The valve seats have been cut using a Newen Fixed-Turning Valve Seat Machine.  (The same machine that top NASCAR and NHRA teams use.)  With the valve seats cut with the Newen Machine you get a lot better valve seal.

 

A video of the seats being cut can be seen at https://www.facebook.com/121753991197977/videos/1560395474000481/

 

The head comes with good YF valves, Legal Race City Springs, Valve seals and Light weight Retainers, 2 rocker pivot bolts, push rod guide, rockers and head gasket.  

 

The installed height has been checked and set.

Cut and Decked and ready to bolt on.

 

All Cylinder Heads are heat cycled before the valve seats are cut.

 

What we have done to the seats has greatly improved the airflow.

    Green Plate Clone

    Posted by Brandon Porter on 10th Jul 2021

    With the rising cost of professionally built clone engines I decided to try my hand at a home built clone engine for my son’s Rookie Box Wing Kart. This head came ready to bolt on as described, and when matched with quality parts, our home built engine ran right up front with the “best” professionally built engines. Thank you Page for great customer support and products.
