What about Brodix B1-BA cylinder heads

Pittsburgh said that some of the heads have the valves too close in spacing

He could run larger intake valves in some of these heads, but not others (I think he said not as big an intake valve with Trick Flow heads)

Playing around I did end up cutting a 2.05 and 2.08 valve seat on my TrickFlow heads. It’s not that the valves are closer together but the fact they used smaller seats. The final cuts end up past the seat and into the chamber. Not sure I like that.
