Are these E or S pistons ?

[1980SC]

I know these are not very clear pictures, but they're the best I can do. The motor is a '69 2.0L E, but these look like the S pistons in Wayne's book. Can you tell which they are? Have any pictures of 2.0L E pistons?





Thanks,

They look like "E" domes to me. You can tell for sure by measuring the upper piston ring, I believe it is thinner on "S" pistons. You can also measure the valve pockets as the "S" heads had large valves and deeper pockets due to the cam timing. You could also "cc" the domes but that is a bit of work.

Those valve pockets look too shallow for S's. I suspect that they're E's.
