'68 318 to carbed Magnum 5.2: Check my checklist

Possible slight change of plans:

Found a pair of perfect Magnum 5.9 heads on Craigslist for dirt cheap from a fellow who swapped to cast-iron R/T heads. They've been very mildly surfaced too; not enough to affect intake fit.

Seems like a no-brainer, though that leaves me with the question of the intake. The super-expensive Edelbrock intakes have a Magnum-style outlet, shifted to the passenger side. The Crosswind is a centered LA outlet.

Either of these is a no-go with the 1988 brackets, but Bouchillon offers brackets compatible for one style or another which retains the V-belt setup.

Now the big question though: Should I consider the vertical-bolt Chinese intake, or go punch-drunk crazy and attempt to drill the 83 degree holes in the Magnum heads on my friend's Bridgeport mill so I can use my Eddy Performer 318/360?
