ORIGINAL: DLEVETT Well I just bought a MVVS/Evolution 58GX for this baby.
Now I just need to find a return to center header for this engine.
Once I get the plane in hand I intend to order a Swan-Neck header from mvvs.nl
Scroll down this page to see what's available:

I'll order the velocity stack too just for the sheer bling of it!
