This comment made me question the specifics of my mental model pushrod vs overhead cam engine. I found this site that has three nice gif’s which was exactly what my visual brain wanted to see for comparing the differences - https://www.samarins.com/glossary/dohc.html

Thanks for the comment as it was the impetus for me to expand my engine knowledge today!

Thanks for the link. Like you, it really helped me understand what's going on with all three of the designs shown.
