Victor style big block heads

Sorry if this is an unintentional detail but....
What size is a true max wedge port?
I know the tf270 is 2.63 × 1.34 and that isn't the same.
We have some old asbestos gaskets at work from the 70s... pretty cool but the max wedge port on those are massive (well by bbm standards).
I was tinkering around a few minutes ago and made a 270 port opening for comparison on a wooden shim and compared it to my Hughes valley pan gaskets. There's a break-away portion and the 270 port lines up pretty close on this.
Just has me thinking without touching the floor I could easily get this port on my 240s.
Also just a thought John if you ever had anybody request a 270 port on a 240 trickflow.
