Curious how this turned out for the op. I'm getting ready to do the exact same thing, and there's also sent the smaller camshaft.... which I returned and purchased the l9h factory stock camshaft. I've already deleted the AFM DOD with a Diablo tuner, am I correct in assuming the l9h camshaft is so close the computer won't know the difference? I'm also debating on the tensioner that the l94 has versus the LS2 dampener. Seems to be pros and cons either way with all kinds of opinions. Considering this is my wife's grocery getter and she never revs it up, I'm leaning towards the factory L94 tensioner. Unless of course I get in there and find it in pieces. Coming up on 160,000 miles and have not lost a lifter yet, so this is preventative. It just got accelerated due to either a rear main or rear cover oil drip. I will also be retaining VVT, plugging the oil relief in the pan and changing to a Melling 10296 pump with the + 10 psi spring installed. Upgrading to rocker Trends but otherwise completely stock.
