It also depends on which one of them was having the seizure... or both of them, and the time at which they were having the seizure and the durations of the seizure(s)...

I have also talked to denny about porting my cylinders. He seems like a very nice guy and was very helpful with all the questions I had.
Glad to hear your happy with his service.
A decent starting point should be:
300 mains
27.5 pilots
needles on 4th clip postion
air screws 1 turn out.
Remember... this is a starting point, you'll have to make minor adjustments!
