Your engine number should have the first 2 or 4 digits cast on the side
of the block followed by some digits stamped into the boss. The first two
digits are likely "49" and if it is an early B20, maybe the first 4 will be
"4969". If you give me the whole number I can chase it down for you.

I'd say it is VERY unlikely it is a B20A, unless it was separately imported
into the US.

I would set the valve clearance at 0.020" although some guys prefer 0.018".
Bigger clearance = less chance of burned exhaust valves if clearance closes
up.
