Valve Springs etc
Is there any benefit to having valve springs, retainers etc, all the items that are usually upgraded when doing a cam swap, without swapping the cam?

If the engine was high enough mileage to warrant some refreshing maybe. Stock cam, the OE LS3 blue springs are a good choice. PSI also has some beehives that would work good with the stock cam, and a mild performance cam if you did that some day (PSI 1511).
Maybe pop a cover off and see if you have yellow or blue springs. The blue are better. The blue springs are a great stock spring... but, limited in lift to very close to stock. If you have any inclination of maybe someday putting a mild cam in, could put PSI 1511s in and they will work with both stock or mild performance cam within their lift limit which I believe is around .620". They would work great with a cam in the .570-.600 lift range. A bit overkill for a stock cam but won't hurt anything. You might lose a couple hp going to a slightly stiffer than stock spring, but probably not even noticeable. That PSI beehive has been used forever in endurance racing , I know Katech uses it and sells it. |

You can replace springs if over 65,000 miles anyway. By installing new valve springs, it will give sharper acceleration and increase rpm by 200-300.

I highly recommend upgrading valvetrain parts when doing a camshaft swap. Most Camshafts will have a required, accompanying valve spring.
And it's worth upgrading while you have the engine opened up. I wish I had upgraded more parts in mine while doing the camshaft swap. At a minimum I recommend springs, and pushrods.
