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

 

Stock LT1 studs are 7/16. Sorry I cant help with the other questions.

 

They are 7/16 on the bottom but 3/8 on the top, so most people would say they are 3/8.

 

ok sooooo..... 3/8 inch rollers will work in stock. I hope they aren't 7/16

 

My fault, was thinking of LT4s. Either would work though.
