Intake Port Tumble

A word on the bowls... Again, volume is more important to me than shape. You do not want the bowl volume too large if you're not porting the rest of the port a bit too. The shape you have is fine and in fact a nice taper to the seat angle is a good thing, epecially for low and mid-lift flow.
BTW - years in business mean nothing. In fact, a lot of really old shops plain suck.
