Generation IV Internal Engine - should i put stock rockers back on???

I am currently running comps XER273HR-14 for my cam
Cam Specs---INT EXH
ADV DUR: 273 279
DUR@.050: 224 230 LOBE SEP: 114.0
VALVE LIFT: .581 .592

I am told that it wouldnt be suggested to run a higher ratio rocker on XER lobes. is this true and if it is what potential damage could it cause??? Currently I have Comp's 918 Springs, and 1.85:1 rockers. I wanna know if I should just try and trade someone out for a set of 1.7's?

You will be fine. I'm running XER, and renegade lobes in my LS7 and they're 1.8 ratio rockers, and not a problem. You just have to make sure that your valve train geometry is squared away.

Either the rockers or the valve springs need to go. The lift on the exhaust valve would be .644 using the 1.85s; that's way too much for the 918s. Plus, unless you have ported heads, there is little need to go much past .600. I'd swap out the rockers, and keep the lift at a reasonable level. You could also swap to a dual spring, but with that type of cam, it'd just make for needless valvetrain wear. I doubt that the valves would hit the pistons, as overall lift has zero to do with that, but those rockers move the valve off the seat quicker which could theoretically cause a problem. I'd say it's unlikely with that cam, though.
