Nice
Is there a reason you didnt make it equal length? or close to it?
Also, im not sure if you've seen it yet, but AMS is selling a cast SS 4g63 bolt pattern exhaust manifold flange. Its a nice piece because it has the runner transition built in, so you can start your runners with schedule 10 without having to worry about welding them into the ports and re-shaping them to fit the oval ports.
