Roller cams don't ware like older flat tapet cams. As long as you inspect it you should be OK, also make sure you put the lifters back on the same holes.
You better double check your parts. Aren't the 787 LS1 retainers? For LT1s I've used the
795 retainers, which are only in 10 degree. These give you a +50 to get the correct install height (1.75-1.80), but you may not be able to use SA rockers are they will ride on the retainer, not the valve tip. So you also need NSA, guide plates and hardened push rods.
Since you're near 550 lift, (544 lift W/1.6 rockers). I'd suggest looking at something like the Crane 10308 kit ( dual springs). I'd double check with Crane, but I think they're good for your lift and fit the heads without needing machining.
But if you want Beehives, look at the following parts:
614-16 Locks +.50
4705-16 Locators
795-15 Retainers +.50
503-16 Valve seals
47530 Shims
Also make sure you check the spring install height on every valve. Few cases we had to shim allot of them to get them all at the right height on stock heads.
