Engine problem or normal?

[1stford]

I’m in Need some flat head experience. You can look back at any engine pictures on my restoration thread if there’s additional questions. So everything is up and running, seems to be running well EXCEPT I’ve got some anti freeze coming out the overflow when I drive. Doesn’t look like a ton I can just see it on the frame. It’s not running hot, oil looks great but oil pressure does seem low, it has since start up, about 5 at idol and 12 when driving. Is all that normal for a stock 8BA?

Thanks.
