Are you sure they are L 2165F? I´ve only found something about L2166NF (former L2166F):
If yours have the.125 inch dome,too, they should be pretty much the same I guess.
Compression ratio: 11.06:1 (58cc heads), 10.23:1 (64cc heads), 9.74:1 (68cc heads), 9.31:1 (72cc heads), 8.92:1 (76cc heads)
Head type: .125 in. dome
Ring size: 5/64 in. top/second ring, 3/16 in. oil control ring.

Baumi's specs should be pretty close. The ring size is the same for L2165F-30 so the compresiion ratio will vary depending on heads used but his numbers look pretty good.

Hey Fritz...might wanna get ahold of Glenn Hayes, posts here as Ahotrod. He use to work for TRW and may still have his old books and catalogues.
