I get to ask the most stupid questions of all of us. Newbie K20 member with new ride already unimpressed with his d17, wanting to swap to a k20a. Is this possible? Dart block okay? I want to piece this one together myself. Money isn't plentiful, it's just there. Best parts/brands(Dart block?, Crane cams/gears?, etc.) Just getting started. Someone advise, everyone else laugh.
