Valve bodies w/PTKD interchange ?

Question : Will all valve bodies with PTKD interchange into small block 727's ? What years (up to ?) will work ? Slant six? or 904/998 ? What about dodge van 1987 ?(there is one locally). Just need some input from someone who might know. My trans is 1964-1967. Built before the pan rail date codes were used. It's DOES NOT have an internal shifter cable. I do not mind changing the NSS over to the 3 pin type (mine has single post).
