I believe my 75 L-82 had 202/160 76cc heads with guide plates as std.

The L82 head is the same casting as the L48, but it has the larger 2.02"/1.60" valves. The casting number is 426624 or 462624 (can't remember which). They are large-chamber 76cc "smog heads" and are prone to cracking.

The L-82 option replaced the LT-1 option in 1973.
