What big block cars would have a yellow tip and what are the part number for the pvc valve for the camaros and Chevelle high performance cars

I think pretty much all the big blocks in 69/70 had the yellow tip. I know for sure 396 motors did.

Most hipo PCV valves were the CV746 purple valve.

But the markings on the yellow tipped sticks varied over the years....
