I believe you're thinking of the pre-magnum... Everything I've seen says ALL
Magnum V8 heads use 1.925 intake and 1.625 exhaust .. the pre-magnums used
to be 1.88" for 318, and 2.02" for 340/360, with a 1.60" exhaust... If
you've seen information to the contrary, I'd love to know it... I don't like
being wrong, but it's been known to happen... :-)

Nada on that Gary. The Mag 360 heads have different valves sizes.
