BBM
Personal opinion. the BBM blocks, heads and intake are likely the best of breed FE components available today, especially right out of the box. I got lucky and had a tour of their casting facility in Korea. The foundry looks as clean as an operating room — stunning for a foundry. Very impressive operation and very easy to talk to people.
