Did you or the shop do the proper cam break in letting it run at 2k for 20 minutes or what ever the cam manufacturer recommends.
Usally after that and tuing you change the oil and take it for a drive. Usally i use zddp aditive for the first few changes. But thats just my insurance plan. But break in lube should be flushed out in first oil change before it get hot in traffic and normal driving.
