NO NEED TO SHOUT LOOSE THE CAPS.
Sounds as if the heads or the block or both have been milled some what, you`ll likely need a pushrod lenth checker and custom lenth pushrods.

I had the same condition with Edelbrock alluminum heads on my BB Chevy. I had to replace the studs with longer ARP studs.

The rocker fulcrum need to be on the root of the stud no threads part.

I have pretty high pressure valvesprings. I originally had ARP regular length studs. I kept breaking them. I switched to the studs that are designed for roller rockers, and haven't broken one since. They are approximately 1/4" longer. That will give you more thread.

Just make sure your valvetrain geometry is correct. With excessively milled heads, you may need different pushrods.
