What are the absolute largest valves you could possibly put in the 350 head?

I realize TA has the 1.94 and 1.55 valves availible, but I was curious as to just how much valve you can fit in there, a 2" valve would be nice.

There is not room for larger than 1.94 and 1.55 since the valves will hit each other if much bigger. Look in the pics and you will see what i am talking about. It may be possible to move the entire valve guide over to add room but not worth the trouble as people have made over 550 hp with the 1.94 and 1.55 valves (or over 1000 hp with boost).

I have 1.92 and 1.55 and there is only .020 between them ....not much room for more than that
