my first cam break in

Finally today is the day that i get to hear my new engine come to life. This will be my first cam break in. Ive read alot and watched lots of videos. Still very nervous. I have alot invested and quite frankly i dont have the funds to start all over lol. Im looking for any pointers from the old timers amd experienced guys. I wont be firing until this afternoon. Still have a few more things to button up. I will have the garden hose there to spray the rad if the temp gets up. Im also going to run a box fan on the grill. This is a comletely new setup so i dont know how its going to react. Thanks in advance guys. Ive gotten alot of help from this community along the way and i appreciate everything guys
