Power brake conversion proportionate valve question

[Leinhit]

I don't have a master cylinder on the firewall at all but it was the old single pot.

I may be misunderstanding, I thought the new vacuum brake conversion had a proportionate valve attached to them on the side of the master cylinder already so I was asking if I just needed to take that off and run it to a distribution block. But I could be misunderstanding and it doesn't have a proportionate valve on it at all?

I could just get another manual break single pot for $75 off Amazon but seems like throwing money away if I want to go to the power brake upgrade anyways at some point, this is my project truck I have never driven it ever but I'm getting close..
