they have screwed in studs which is good but the stock springs are only good to about .460". I just put in an lt4 hot cam (.492 lift) in my vette l98 and new springs that are advertised good to .570 but i wouldn't trust them over .520. I also had my valve guides and the collars on the spring cups milled .050 to clear the retainers.
