4v heads they have a 4 carted on them
What i have is a 351 d block, now i was told it has not got 4v heads and i know where to look for the 4v casting on them and it is blank. Now that the motor is out of the car i notice a 4 below its usual spot, mmm i thought.Well today i came across some information.
(The main difference in the two 4V head options, one was open chambered and the other was quenched or closed chambered and was identifiable by the #4 in the upper and lower corners of the head.)
My #4 is below does anyone if this means they are 4v heads
