Look for the small water line from the head to the block. If it's short (1 inch or so), it's a 170. If it's longer (2+ inches), it's a 225.

If you come back with the block casting number, you can get more info too. I have the info somewhere and can look it up if needed.

Valve covers interchange, so that's not a good indication.
The bypass hose is the quick, sure way.
Check out slantsix.org for lots of great info.

Rod is right, i did change my cover for an ribbed old looking one, fits perfect(1966-1979), so not a good hint.
