I usually find 8-10 BTDC is the closest point on the exhaust and 8-10 ATDC for the intake.
Its best to check it at 6 8 10 and 12. you will see it cet closer and then further.
Piston to valve clearance depending on your springs and the major intensity of the cam grinds. Typical is no less than .040"-.050" on the intake and .050"-.070" on the exhaust.
Stay to the high side if the major intensity is below 24.
