Hey guys, I picked up a set of harland roller rockers from a buddy and I don't know what size they are. If they don't fit then I am selling them and if they do then

WHat size studs do I have in my stock LT1 aluminum heads and how can I figure out the size stud the rocker fits without popping any valve covers?

I have an older camaro with steel heads at my house would those studs be the same size as the LT1? I could pop those covers and check a lot easier if that would be a sufficent test.

Thanks! Kurt
