Round port Vs. Rectangle port

[SuperDave1965]

I just have a question about ports in heads.

I have a header for sale that is rectangle port,and the gentleman that wants to purchase it from me has round ports on his head.

My question is will the header designed for rectangle ports ,work on a round port head?

This has been discussed lots of times. Do a search with some key words like "header round square" and you will find all you need to know.
