The problem with original Hemi heads heads in relation to timing needs is the total lack of squish.

And if you do get the piston dome near enough to the chamber walls to generate some turbulence then the flame travel goes to Hell in the Hemi head faster then the added timing can make up for!

Just go look at the power improvements in the aftermarket Harley heads designed for squish.
