Blau911 -- Did they also by chance sell you a lightened flywheel? If they did, going back to a stock flywheel may help to keep the motor from fluffing when you release the clutch from a dead stop.

DTW -What year are your heads? They will generally have a month/year cast inside an oval on the bottom (cylinder) face of the head, on the intake side. BK911 has posted some head flow data and it looks like the bigger ports will (among other things) flow more at maximum lift, but don't have as much affect below that. He checked a 2.4TK head that I had with 30mm intake ports and they really seemed to max out at about .35 - .4 inches of lift. We don't have any 32 mm T/E heads to test so I don't have any data on that version. (If anyone wants to share a head to be flowed, BK911 has been posting the results.) Based on the data that we've gotten so far, I suspect that smaller port heads may not respond to the extra lift, but will still respond to the longer duration. I'm not familiar with the Crane 288 cams, what are the lift and duration?

As far as your ports, it's a small matter to get a metric ruler and measure your ports (assuming manifolds have been removed. You can also measure it in inches and multiply by 25.4.
