Those appear to be a set of TRW (look to be forged) stock replacement L46 pistons
About .100 dome height, depending on the heads, somewhere between approx. 10.5:1 (77cc) to 11.?:1 (64cc) ish
The .030 means the engine has been bored oversize .030"

I don't know the cc of the pistons but if I had to guestimate I'd go around xxxx (see 63Mako's post below) but I've never measured one
A 2403 used to be sort of a standard replacement, specs for those should be out there somewhere

The L48 had a small dish with the valve reliefs (4 I believe) and 76cc heads (you could get close to 9:1 with a set of 64cc heads)
