I picked up a 3.3 intake I need to get ported to 38mm. I also read a couple of old threads about extrude-honed to match the flow. The posts are pretty old, who is still doing this? Is this still the way to go? I was thinking of setting up the intake on my mill to enlarge the opening, but I'm getting there is more to it.

This is for my hodge-podge 3.3/3.0 motor. TK ported the heads, aluminum injector blocks and 3.0 intake (CIS). The current i/c set up has the i/c in the firewall so the 3.0 intake is fine. If I want to try another i/c in the stock position I need the 3.3 intake. I test fit a Andial/Garretson 3.0 i/c (for sale) but it sits too high.
