I see you are running a flat tappet cam. I will tell you this in case you don't know make sure you use diesel formula oil or racing oil that has zddp (zinc) in it or you will wipe out the cam lobes in short order. All the standard oils nowadays are formulated for modern engines with roller cams and don't contain zinc because it kills the catalytic converters.
i am using just a 10w-30 right now, should i convert to the diesel formula oil or racing oil that has zddp after i change my oil for the 1st time?
NO -- CHANGE IT NOW... or at least buy some zinc additive - several brands - one of the best can be bought from your local GM dealer parts department...
It's the very first few times you run the motor that it all has to work right and seat/break in. Don't wait on this.
