Yeah these are the 185cc ports with 64cc chambers so I am quite happy with those specs. However there's some nonsense about them not being able to be run with roller cams. That is not an issue with this flat tapped block/cam combo, but in case I wanted to move them to my other spare roller block... just thinking ahead
also they don't recommend reving them above 5,500 RPM which I don't expect to be an issue on this ol' mouse!
IMPORTANT NOTE: "E-Street Cylinder Heads are equipped with 1.460” diameter valve springs that have been tested to 5,500 rpm with
an Edelbrock Performer camshaft. DO NOT EXCEED 5,500 RPM WITH THESE SPRINGS.
Higher operating speeds may induce valve float
which can cause severe engine damage. Performer RPM heads are recommended for higher engine speeds. Check the spring specs for
your camshaft before installing these heads."
