Mmmmm torque plates. In my almost 47 years of racing I’ve had one block (my R3 block) that has ever had a torque plate bolted to it. And I think I’ve had some pretty good running engines.
What ever works for you. I have a stack of torque plates, some I have had made. My engines run fine and last forever. My small block plates came from Ed Hamburger, but what did he know. That was a determinate on who got my work. If they didn't have plates I moved on.
