DISCLAIMER: NOT my video and I do NOT even know these guys. EDIT: Sorry I didn't make the connection to HAMBs own @ronnieroadster until I saw his avatar in this thread LOL. Then the lighbulb came on and I realized he was on the HAMB. post 165 https://www.jalopyjournal.com/forum...-official-thread.1221258/page-6#post-14131037 Wow very lucky this week finding great videos. This is mainly about the Ardun heads, which I have seen a bunch of all done but never the "insides". But a great bonus for Flathead owners. In the beginning they talk about the block and the differences between the sides of the blocks and some hints on how to get the heads to seal better.
With push rods to open valves located in cast aluminum cylinder heads but since you asked about a set. You need one for each side of the Ford flathead block you are wanting to attach them too.
