If you're looking to save money, you can start by canning the Fluidampr. Haven't heard any good from it, and all the highest hp 6.0s are running stock balancers. That tells you something there.
Port and polished is nice for air flow, but even when done to it's limits, it'll gain roughly 25rwhp give or take a few. So you have to weigh the cost versus the gains. I had the option, but held off when doing my build.
As stated above me, always good to have a solid shop doing the work who has seen and worked on 6.0s before. Sounds like you have that covered, which is great.
Guessing that since you mentioned supporting mods, that studs are already in place. Make sure they are torqued to 270 pounds to hold strong with the extra fuel and (minimally) added heat you'll be pushing into the motor now.
Other areas- check both pumps, high pressure and low pressure oils. Make sure your electrical wiring on top of the motor is cleaned up and not wearing. Look into your FICM
, possibly put on a tuned one while you have the motor down, won't hurt to throw on a mild tuned FICM
from Innovative when it goes back on, to back up the 190s you're putting in.
I'm just thinking of simple, yet effective things that won't break the bank. Sounds like you have some good hard parts in place and now you'll have some new goodies to back them up.
Hope this helps some
