My compression is good and I checked when I started to notice the white smoke before the gasket blew
FWIW:  Engines with water jackets can blow white vapor out the exhaust, when head gaskets blow.

I followed this logic. Put 500 miles of easy riding i.e. no test pilot type of riding; and then changed the oil and filter, did the same at 1000 miles, and will follow this by a 3rd at 1500 miles which will happen this weekend.
Note: when I passed the 1000 mile mark I was more lenient with my riding giving it a bit more throttle from time to time, but not going crazy; I must add that I'm more of a cruiser than a rocket jockey and all the while adjusting and double checking as needed.

This method of breaking in a motor may seem a bit extreme or long winded (it did to some of they guys I hang out with) but when you've had to pull a motor a couple of times, you get really cautious!!!

Good luck!!!
