So we shipped the lower intake to Fox Lake for Robart to port-match to our newly ported heads. He charges $150 for that service, and an additional $50 if you have a dual-plane manifold for a carbureted application. Port matching ensures that there is no mismatch between the intake, the intake gaskets and the ports in the heads. And this can be worth 10-20 hp depending on the application and the degree of mismatch. In our book, it is money well spent.
Check out the before and after photos of our heads, and follow along with the installation process. Check back next month as we put the finishing touches on our 347, install it, and run it on our DynoJet chassis dyno.
