Change the oil- but not the filter- fill the coolant up, and then take it around the block- get it warm.
Then look at the exhaust, check the coolant. If it all looks ok, go a mile, turn around, come
back, look again.
Then if THAT looks ok, do 10 miles on the freeway, and see if you can get home!
Take some water, and your phone and AAA card.
You won't do enough damage in 10 or 20 miles to offset the hassle of pulling the head when it didn't need it.
