Edelbrock valve spring replacements

Thank you maybe these last ones u recommended will drop right in ??
I think a comment was made about when using double springs they
LS sometimes want fit without machine work your thoughts ???
There's no reason I can think of why they wouldn't. You will need the correct spring locators and retainers, but be careful about buying an LS spring kit, as LS engines use 8mm valves and the Eddies have 11/32" valves, so the locks won't fit. However, it may still be cheaper to buy a kit and source the correct 11/32" locks than buying everything individually.

I use Crane stem seals (part 99820-16) and these have an OD of .620", so will clear the ID of the small spring, which is .665" for the PSI and .676" for the Manley.
