OK, I had some guys over for the holidays, and learned a bunch about port matching. And looking at a head I had lying on a bench, I can see a whole bunch of head that forms a flat wall blocking the air flow from the manifold to the intake ports.

Question to the other 2.2L engine builders out there, how much of that do I remove (up to a depth of 1" per GCR)? Do I go back straight from the head along the bottom edge of gasket?

Will I need to increase my carb jets to counteract the leaning out of the air-gas mix?

Planning on port matching on the engine I am going to rebuild this year.

Thanks, guys.
