| I especially like the equal-length routing of cylinders 5 and 6 straight exit into turbine valute; something possible with the flexibility of tubular construction. You're right....a shame to cover them up. 
Don't kid yourself, though, this is way cooler. Someday I might finish my '91 slicktop w/ Garrett T04B 2860's with T3 externally gated turbines. Our youngest daughter (21) just moved out and may be time to finish the project.
I know you didn't ask. I saw the "manifold pic request."
