I have a HF CRX but im not sure what head its has. All I know its MPFI, DX block, ls ecu but im not sure what head it has. All I know is that it says 16 valves on cover. How can Identify this head?? Thanks

 

The valve cover dosent mean a thing, as those are interchangeable.

There is a code stamped on the side of the head, just above the exhaust manifold. That will determine what head it actually is. Figure out what is stamped on it and get back to us.


D-series with a ls ecu? You will be running way rich. Get a sohc ecu.

 

it is running rich
