I just went thru this too. Luckily my car is still street registered (but not truly streetable) so I was able to throw a muffler on and drive around the canyons a bit. The usual process, varying revs but not slamming into the limiter at WOT and not cruising steady for long. This was a very limited break-in but it gave me added comfort it wouldn't be DOA when I got to the track. Then, I went to the track! Then, oil change and valve adjustment.
