I stipped the 142 blower off my chevelle and selling it. Then proceeded to pull off the heads for a port/cleaning job. My heads are DART 165 cc iron heads with 72cc chambers. Im not looking to port match but to work the short turn into the chamber and massage the camber area. My question is what it is.......Is it worth the extra money to install larger valves on these heads? Will it really give me some added flow or not really?

Anyone have some good feedback or flow #'s of before and after testing on similar heads? Thanks guys.

I would sell the heads and upgrade with a new set. With 165 cc intake runners the heads are not going to care if they had 2.02 or 1.94's.
