True, so let's apply that logic to every single sponsor on BHQ whom you haven't seen with your own eyes port a cylinder. So your saying that Redline, HJR to name a few also do not port cylinders, or we have no proof they do their own porting. So in short I agree with you that unless any of us have actually seen with our own eyes someone port a cylinder we cannot say for sure that they do their own porting. If I never see him actually port my cylinder, I'll still be perfectly happy knowing that "his" port and pipes will still out perform anything from OK. Apples to apples of course Hahaha. God I love these threads!
