I agree with Monte. I prefer not to go with the big stroke but have been convinced to try it. I also have a new crank on order to make this a smaller engine later. I will be curious to see the results of what going to a smaller cube deal will show later over this big one. If I were you I would look to stay at or UNDER 4.500". I am not a fan of even the 4.5" stroke deals. Most don't seem to run that well. Just my .02

Bore makes power. Unfortunately in a Mopar we are limited there for sure. My new deal is a Predator motor but these heads are still "nothing special" for sure. Just the only option to date I have not tried. The sad part is I will be giving up 150ish+ HP over what my 99 Hemi made at 499". FWIW that was a 4.700" stroke deal.

My new deal made peak at 7600 when we has it on the dyno.
