this may be a stupid question

Seems the Aussies have all the neat slant-six stuff these days. I was thinking one of those M90 blower hyper-pak manifolds would be an exceptionally sweet piece. But, I'm not about to pay $100 just for shipping on a single part. I was thinking that it'd be possible to stretch an aluminum 2-bbl manifold with a bit of engineering work...and a lot of JB-Weld.
