Like any head, polish the ports.

Those are actually a nice, inexpensive upgrade for a 302. They used to come on Explorers that had the 302 in them. It basically upgrades the heads for a GT to be similar to a Cobra.

Also, if you can get GT40 the upper and lower intake from the Explorer you will be getting basically what came in the Cobra, too. Another "cheap" upgrade.
