WR Tappet Blocks. Made by Flathead Power. These tappet blocks are made to run roller tappets. Made out of gray cast iron. You will need to get angle ground cam lobes from Leineweber so your lobe angle matches your roller angle. ** You can not run the OEM cam lobes for the solid shoe style WR tappets with these! ** The profile will not work with the roller tappets. 
 I will have them at the 2025 AMCA Sunshine Chapter swapmeet in Daytona.
Pictures coming soon
