looking good. what is port matching i have never heard of that?
It's the long way of saying porting. You smooth out the casting inside to get more flow. You can gasket match so that the ports are as large as the gasket allows, or you can take out more material and just modify the gasket.

Correct ... Intake will probably take a bit of gasket to enlarge the ports a bit. The exhaust will be gasket matched.
Newer cars have come a long way and a lot of the joints between the intake manifolds and the head are very close to the same size (matched) but .... back in the day they were not.. so there is one side that is smaller than the other making a ridge ... This ridge between the two is bad.
Porting = taking material away to create a better/increased flowing port (some of this will be done on my head)
Port matching = matching the ports or holes in the intake manifold and head as well as exhaust header and head (this is the main thing being done on my head)
