wondering if you can run a stock cast iron high rise intake with these heads I am running a sbc 421 in a street stock racing class and we have to run a cast iron intake at some tracks. If you can't run a stock type intake is there anyone around that can modify cast iron to make it be able to work? Thank you

The intake ports are too tall on these heads to use any stock intake unless you add material to the top of the intake manifold. Check with some cylinder head porting companies for the possibility of modifying your intake to use with these heads.

23 degrees is the stock OEM valve angle. Many racing sanctioning bodies require stock valve angle of 23 degree.
