I've just been through all this, so here goes . . . Edelbrock heads will accept any LS-style beehive and most LS double springs, as the installed height is the same 1.800". You can also increase the installed height of you standard Edelbrock springs to 1.820" to handle .600" springs (see below).
LS beehives will handle just about any hydraulic roller cam with .600"-.650" lift, and all spring manufacturers have them - so plenty of choice.
Valve guide outer diameter is .545" (most LS beehive spring locators are around .565"-.570" internal diameter), and you will need a matching set of 11/32" retainers and locks.
Spring pockets (as machined) will accept up to 1.480" spring cups and shims, so if you decide to go for a double spring, bear this in mind, as many have diameters of 1.500" or more and won't fit without machining the pockets. You basically want a spring with an installed height of around 1.800" with an outside diameter of up to 1.480" and inner spring internal diameter of more than .545" - which still gives you plenty of choice.
Standard LA/Magnum head Edelbrock springs are part #5767 with an outside diameter of 1.460". They are actually a Ford spring with a seat pressure of
[email protected]" and rate of around 360lb. You could try to make them work with a .600" cam by using a set of +.050" locks and some shims. You might even get lucky and find when you remove the springs there are enough shims underneath (they are shimmed from the factory) that can be removed to get to your installed height of 1.820" without the +.050" locks. This increases max lift from .580" to .600".
Whether the standard Edelbrock springs can handle your cam or not depends on the cam specs and how old the springs are (and whether or not they've lost much pressure).
Beehives are your best option, IMO, and Lunati has a couple of LS springs that drop straight in and should match your .600" cam (assuming it's a hydraulic roller). Have a look at the 74818 or 75818 (nitrided) LS beehive springs - they're rebranded Pac 1218 and 1518 (nitrided) springs and are the spring of choice for many LS hydraulic roller engines.
You can also buy a complete kit, which includes springs, spring locators, 11/32" retainers and locks. Lunati spring kit 74818K2 has 7 degree locks and retainers, and 74818K5 has 10 degree locks and retainers. Kit 74818K6 has +.050" locks.
If you prefer a double spring, something like Lunati's 74721 pro series will fit and is for similar applications to the beehives mentioned above.
Let me know if you have any questions - with the right parts, it's a very simple swap.
