Bunches of port work, but back then it was still going to be naturally aspirated. So it could have more port expansion done to it, tiny bit bigger valves. Has 2.02 int, 1.60 exh with a 5 angle grind. Also port matched the intake. Next time the head comes of for an upgrade it's getting titanium valves and have everything heat coated that can be.

Oh yeah, and once I get some real $$$ I'm gonna take this POS off and put on a fourniner head.

I thought I'd throw this in here. The ports have been changed slightly since it was flowed, but not alot.

Well, keep in mind I have 2.6L to feed through this one head, so I'd actually like to see a bit more flow. Maybe go to a 2.08" valve on the intake side. Definitely going to open up the ports more next time, on the exhaust side too.
