Spring size???

Hey all!! Happy Holidays! I am curious to know from some experienced people here about the valve springs i have. I have a 455 olds with a Comp XE274=.520 lift. My machine shop put double springs on. Do you think i really need dual springs? I was thinking i only needed single springs and am wondering if this was the cause of my Brand new cam wiping out lobes. Thanks!!! Also, i have no idea what brand or size for that matter they put in, but do know they are double springs.

The number of springs (single, dual, etc ) has little to do with actual spring pressure. Just because you have dual springs does not mean they are very heavy in seat pressure.
Generally, for performance applications, something between 110 and 120 lbs of seat pressure is adequate for hydraulic flat tappet cams. I don't like to exceed 350 lbs at full lift with a hydraulic cam.

I guess what I'm getting at is use the springs that are recommended by the cam manufacturer, as there is more to valve springs than meets the eye.
