And a word of advice, use a good quality break in oil after a rebuild or after a fresh top end.
I made the mistake of running regular oil after I rebuilt my 375 HP 327 years back. I went through it top to bottom with new everything, and I put 10W40 oil off the shelf in it, and drove it. Rings never seated, and I wiped out the cam after less than 50 miles.
After that EVERY time I rebuilt an engine, no matter if it was a bike or ATV engine, or a car engine, I put break in oil in it, and went by the manufacturers specs, and haven't had a failure yet.
And yes I know oil is a lot better than back then, but it's still good practice to do it right the first time. That way there is no need for a teardown.
Old type American V8's are known to wipe out cams if you don't break them in carefully. High zinc/phosphorus oil never hurts.
