Jeff, If these are 72 heads and the holes are round, most likely they were machined at some point for push rod guide plates. This is common and a very easy fix. I have the guide plates in stock for $39.95 a set.

I hope all is well. I found '72 heads for my 1971 Javelin...... the "guide" for the push rods is a larger diameter though. So, my push rods "dance" now and the rocker-arms won't always stay on them. I had to buy .100" shorter push-rods. As far as I can tell, I cannot use larger push-rods because they wouldn't fit my lifters, etc. So, I must come up with a solution. What would you suggest? The only thing I can think of is to put "sleeves" in the guide (to narrow the diameter). Problem is, I have no idea where to get this material or who can do it. I've also considered roller-rockers but Jeg's and Summit do not have all the parts I need....... What do you suggest? I'd appreciate any help or suggestions you can give me. Have a good day!
