NEED ADVICE!! New Timing Chain & Head Gasket

Hey guys, I just have a couple questions to ask. I just replaced my head gasket because I was loosing coolant in my oil, I went ahead & replaced the timing chain, sprockets & tensioner. 2.2 ecotec. This is my 1st time doing something like this but ive done minor work to my cars & toys before. I followed everything I read. The car started right up & is running very very smooth but it does have a little vibration, more than it used to. Its not like its missing, just a vibration from it running & im just curious?? The other thing is I let it idle for awhile to see if it got hot & it reached 217 then the fans kicked on & cooled it down to 190. While driving it stays between 186 & 200. Is this normal? It never used to reach more than 205 at idle. I have put about 200 miles on it since the job. Thanks for the advice!

You're fine. You can try re torquing the head bolts just in case but I'm sure its not too big of a deal. Make sure the motor mount bolts are tight too
