ZZ4 stud girdle
Has anyone found a stud girdle for the ZZ4 heads? I understand they have a different stud spacing.

ZZ4 heads are no different, stud-wise, than the corvette "113" castings, considering that is what they are based on.

You can't run a normal girdle with the centerbolt valve covers - unless you know someone who can get you LT1 factory race car parts. You need to go 7/16" studs like I did for more stability.
