Default ID'ing valve springs

I'm putting together a 6.0 iron block with l92 heads. The heads are nib from scoggin dickey and have been decked a little to bump the CR to 11 to 1. I'm trying to ID the springs, they have a med/dark blue stripe, single, beehive design. These sound alot like Comps 918's but did chevy ever make a design like this? I don't want to run the springs unless I can ID them, hate to destroy my new motor.

I can get pics if there needed. Also the engine came with a assa 550 lift cam and everything else was hi spec, arp etc.

Thanks!!

Possible but the mounted height isn't correct. Mine are 1.82 to the top of the spring.

If you got the L92's new then thats what the springs are, just stock L92 springs. I think they are good to about .570 lift or so. If you search around you should be able to find the lift rating. My L92's had the same springs when I bought them new.

I didn't buy them but they are new from scoogin dickey, the part number on the boxes = bare head castings?????

12615361 is the number off the box, they were assembled with springs and valves when I got them. That number doesn't cross to SD anymore but it does cross to other stores as a bare head. Not sure when these were bought, prob awhile back.

Here's some pics....
