I'm sure cascade knows what they are doing and they aren't building my motor. port work and cut domes to my specs but I choose everything they are the only people close that I would trust to port my cyls and cut domes. Maybe one day I'll have enough money to let a "builder" do some crazy stuff maybe i would go to redline i know nothing about them or cascade really other then the bikes they have built are nice but for now just a plain Jane 4mil dune bike not going crazy with it just parts port work and cut domes. Thanks to the people that were helpful and to whoever I pissed off, oh well sorry bud you will get over it
