It appears to be a LM1 head. How deep is the squish band. It appears to be pretty shallow. Many think .040” is minimum height.

To confirm you just need to check the valve sizes....certainly looks LM though

The diameter of the valve seats. Should be slightly over 44 and 37 mm.

Without the valves and a caliper it's hard to check. the 6mm intake bolts holes indicate lemans heads,

Here are some comparison shots I took
