Update...
After some more measuring and careful shaping of the SSR, the heads are flowing well right up to .700 lift.  Peak flow is just over 290cfm@28".  280@.500 and 288 @.600 with next to zero loss at lower lift values.  More importantly, the gains came with minimal change in CSA.  I am pleased with these results.  These heads should work just fine on this 427FE.
