are you SURE the rockers aren't contacting the covers? look for dings, etc on the rockers and the covers. Otherwise just roll with it, my solid cam sounds like a sewing machine at idle with the covers on.
i run a solid roller in the race car. it does sound like a sewing machine, but i really cant hear it due to lack of exhaust. if nothing is hitting and valves are adjusted good i wouldnt sweat it. it might just be the aluminum magnifing all the other valvetrain noise...

I doubt there is a problem with it.. The stock valvetrain on these cars is loud as hell so I'm sure a solid roller setup would sound even worse.. The yella terra rockers on my 402 sound like ****.. I've got jessels on my 408 and it sounds as quiet as a church mouse even better than stock rockers. I say LET IT EAT!!!

Honestly my old solid roller 414 (iron block) was amazingly quiet in the valvetrain, T&D rockers and 3/8 pushrods. Even with a fairly quiet exhaust the valvetrain was quieter then a lot of hydraulic LS1 cars I had.
Maybe some of it was the iron block but it was a lot quieter then my old solid roller big blocks with mufflers. If nothing is hitting and the geometry is correct what can you do except run it..

I have the Jesel C5R Pro Series rockers, 7/16 pushrods, aluminium C5R valve covers. I am surprised how quiet the valvetrain is. I'm not running alot of lift though 276/290 .747/.770. My vette with a hydraulic cam is way louder. Just make sure nothing is making contact inside the valve covers, check your lash hot and your good to go. Lash on my setup is .021 cold/.025 hot.
