head problem

[jamesi20]

I bought these world product heads for my 350 about 5 years ago...they have been in the boxes in my garage since I bought them.I did open one box and look at the head when I first got them and they were nice.They are cast iron with manley s.s. valves,220c.c.runners,64 c.c. straight plugs.here's the problem,since my frame and suspension are done and my cab is 90% done,I figured I would get the heads out and clean them up to get ready for painting,as my block is painted and I want to put the motor together.well,I was looking at the intake ports and on one of the heads,there is a hole about one inch long and 3/16" wide,thru the port and into the pushrod hole!Do you think this can be repaired? I really don't want to ignore it.any advice would be appreciated.
