There are a few ways you can deal with spring bind
One if you can find diffrent collets ( some call them Keepers ) to raise the
retainer
Or you can have valve made with longer stems ( this is a good idea for use
with a high lift cam as then you don't need thick lash pads
Or you can get diffrent retainers and keepers
I think you should have no problem with spring bind until your over .5 inch
lift . but always good to check , take a 20 thou feeler gauge stick between
the spring coils , and then turn then cam shaft and see if the feeler get
stuck between the coils ....
