Master/distribution block

I recently took a master cylinder and distribution block out of a 2003 Malibu. It is the 2 port design Master. I am currently installing a custom brake setup in my car and am wondering if the Master is proportioning or not and if the dist. block is a straight dist. block or if it acts as the prop. valve instead of the master........

Looking to install two inline Wilwood adj. proportioing valves after the master, then onto dist.block(s)......

Thanks for any help in advance....:)
