Dan,

Are you speaking of the cheap flat tongue inserts or the expensive round ones?

     CHI 4V heads have 4V ports only on the intake side.A  The exhaust
   side
     is not 4V and I wouldn't try to run a port stuffer.A  On iron 4V
   heads,
     we have seen an increase in average power with the MPG Stinger type
     inserts on both Pantera shorty and Mustang long tube headers.A  Peak
     power didn't necessarily increase but the low and mid range picked
   up.
