Responce from Pete @ Zippers

"Jim,

Hello. This is Pete and we have talked before.



The heads that you have appear to be a set of SE 110 heads. They were originally built as our Stage III Heads and set up for an S&S 625 Cam, 117” engine, and had .005” decked off of them.

Now, these heads were done in early 2017, so I cannot speak to the condition they are in now!



If you need anything for these heads, please let me know.


Thanks!"
