Damn Hawk! Hope it's a pushrod too. If it's a valve don't run the car. Most people say it's ok but I say BS. What spring do you have in there? 941's are notorious for breaking in LS1's. You'll need the 918's from what all the guys w/ cams like yours suggest and are proven springs.
Mine ran like crap yesterday too. I hear a tick more like to coke bottles tapping eachother and it doesn't have a rythm either so I don't know what it is. My batt was low so it ran like poo until it recharged. But I still get the coke bottle sound. Had that for awhile and I'm like whatever. If she goes down she goes down I'm running it to the ground until it does.
Then I'll put a little forged 350 in it w/ my heads, intake, revkit, headers, etc and 18lbs of boost.
