port timing

[banshee4201]

i got a 400 68mm cub fully drag ported, 5mm long rod crank, trinity head, 18cc domes, trinity intakes, 38mm keihns, out of frame cpi's with silencers, dynatek cdi. I was just wondering exactly how do i get the port timing just right, and what should it be and how do i check it. just looking for just a little more power out of this motor. i'm running 50/50 110,93 and my squish is about 65 thou. i know thats off. It runs great just wanted to get the port timing rite, Thanks.

The port timing was set by whoever did the portwork. It is determined by how high the ports are cut. Your squish is a little loose, probably work for a drag setup.
