Not really, most BB Mopars, iron or aluminum heads, like 34 total the best that I have tuned and raced 35 or 36 degrees would run very close, if not exactly the same ET, so why run more than you need to get the best performance
I do remember one well known SS racer that had a 415 HP 426 M.W. 1963 Savoy that swore his motor liked 42 degrees total but he didn't build the motors. I found out later why he thought his motor like that amount of timing, a early timing cover used with a later model balancer You have to verify every little thing on race motors
