SYNTAXX... Jim is a good honest hardworking guy. You will not be disappointed. I also got my cylinders ported by him, I chose a very radical port job which is more on the drag side of dune/drag porting but still maintains some dune ability. I am only using stock carbs and its still a night and day difference.. the power is awesome.. I will be upgrading to bigger carbs soon... Be sure to let us know how you like it.
