You can see the RR350 alloy number that was only used in 930 heads, and date code of 1-86 with 1-85 on one of the heads so they are 930 heads made in 1986 and one was made in 1985.
They may be factory machined for a 97mm bore but you would have to measure to see.
I don't see the small bevel at the edge of the squish band on these either?
