427 3 Belt Water Pump Pulley,and Heads Question ?
 

I have a 3 Belt Pulley #14037739 DF with a P on it. Would it be the right one for a 1969 427 block casting # 3916321 with Casting #3964291 Heads ? Also will these be good street heads ?.......Thank You, Bob https://www.yenko.net/ubbthreads/imag...ns/worship.gif
