how to tell the difference between 1.5 and 1.6 heads?

[truckinwagen]

I have a bunch of 11mm heads that I bought from an old guy who was moving.

I think some of them are 1.5L and some are 1.6L

is there a difference in the casting/code that will confirm if they are 1.5 or 1.6L heads?

thanks in advance for the help,

Not sure about casting numbers, but the 1.5 has a smaller oil return on the front of the head between injectors 2 and 3..
