What is the head flow on Edelbrock performer?
28″
All Edelbrock cylinder heads are flowed at 28″ of water, which more closely represents what an engine will see. Beware of companies flowing heads at anything less than 28″ of water, because that is not a valid comparison with Edelbrock heads.
What do cylinder head flow numbers mean?
The flow numbers provide solid information on the power potential offered by the cylinder heads. Why do we use the phrase power potential? The reason is simple. As measured on the flow bench, the airflow numbers indicate only the flow potential of the port.
How is cylinder head flow measured?
Typically, cylinder-head specialists use a flow bench to measure how much air (measured in cubic feet per minute) will move through an area when a specific amount of vacuum is created. A Pitot tube is a small tube connected to a pressure measuring device that can tell you how much air is flowing past a specific point.
Where are RHS heads made?
New Zealand foundry
As the new business grew larger, the RHS operation and name was idled. The intent was always to bring the name and reputation back when the timing was right. The Pro-Topline situation became that opportunity. The New Zealand foundry where the heads are cast is actually a purpose built operation for cylinder heads.

How big is a small block Edelbrock engine?
Edelbrock Small block “LA” with intake pushrod moved over .190″ As you can see, these are extreme flow heads. We have used them on a 740 HP, 392″ engine running pump gas. Flow tests below show results from our SAENZ 680 Flow Bench with a pipe.
How big of a pressure differential does Edelbrock head need?
The pressure differential that a head is flowed at dramatically affects the results. All Edelbrock cylinder heads are flowed at 28″ of water, which more closely represents what an engine will see. Beware of companies flowing heads at anything less than 28″ of water, because that is not a valid comparison with Edelbrock heads.
How much water does an Edelbrock cylinder head need?
