Another O/T.... A check of spring pressure on Edelbrock...

PERFORMER 302 heads shows 110# on the seat. New should be 120# and 320# open. I fear valve float with an X303 cam. Would 6200 rpm limit be safe or should it be limited to something a bit less??? I don't know what the open pressure is.

just that old crane double spring w/no damper. seat pressure should come out about right for those cams.
I might be mistaken, but if I can get these on my GT40X heads I will use them.
