Off-set the cuts and put it back together ( welded Or some other means to seal it up). That would make for some vary tall ports to work with.Bolting the intake & exhaust back on could be interesting If you didn't think and cut the bolt holes in half.
And you would need a VARY good band saw Or better Yet have it cut with a Lazer.But knowing what the inside of Our Chevy head looks like a small issue could be the Port shape itself.A 12 port head I think would much easier then a shared port.
God doesn't like ugly.
