what's missing from your post is compression, head flows, exhaust
intended usage trans gears weight, power brakes etc
post back, if he does not log in drop him a PM

what rpm do you shift- where do you want to shift?
whose cam now?
try tightening up the lash and see if it makes any difference
do the intakes first, if there is an improvement do the exhausts
what lift will your springs take- spring specs

Somemething about two to four degrees more exaust duration works better, Tony Mamo tould us this, if I remember correctly.
If want more, increase the CR to 11.5 to 1, bigger cam and 410 gears. With a five or six speed tranny I'd go with 108LCA.

he could tell if these are latest technology or oldy moldy profiles
I noticed that Lunati did not have special profiles for Chryslers so I stopped looking.

before I go further lots of things can change how much extra exhaust you need IIF ANY (or less)
exhaust, headers, rocker ratios blower, turbo, etc
consider the whole system
but bottom line is the AFR intake/ exhaust ration may be better than stock
or the heads flow so well that too much intake flows out the exhaust (which would also affect your LCA choice)
or to control reversion
let us know what you find out
and thanks for bringing this up
one more thing to be considered
