Grab a 6.4 short block from the dealer and slide it under your heads, cheaper than stroking you current engine and you get a bigger bore for less valve shrouding, very good machine work, already assembled, you can get the BGE or Apache for your choice in compression.
Do you have the dealer part number(s) for the 6.4 shortblock you are referring to?
I'm a newbie at the Gen IIIs, me and my 16yo son (it's his car) are learning though. So BGE is the truck engine, would Apache then be the 6.4 used in the SRT?
