Okay i just spent a total of 10 hours doing my mini-me fuking swap!!! 1 hr for NAPA giving me the wrong gasket, 3 hours trying to find the right socket size for all the bolts... then 1 hr for the distributor.. it was a bitch but its running fine

my timing is right, it starts up but when i rev the engine my head has a whistling noise, when i poped my hood and reved from the throttle cable i noticed it was the timing belt (we spilt some oil on the belt) could that be the whistling noise? also the head when i rev sounds a bit different the my d16a6 head (now D16z6 head) and there is NO VTEC right now, could that be why its a different noise? or could it possibly be it still has to get worked in the oil and coolant and new headgasket and stuff? please HELP!!!!
