All the crane golds for mopars are aluminum rockers running on steel shafts.
Usually fine (for a while) with spring pressures under 600lbs.

if the rod journals are stock Mopar 2.375 size I would sell the rods and pistons and have the crankshaft offset ground to BB Chevy 2.200 size and offset to 4.300 stroke and buy some BB Chevy 7.100 long rods with the .990 pin size and buy a really good set of a lot lighter piston and pins What size rings are on the pistons you have now? If your going to race this motor only look at a skinny ring like 1MM,1Mm,1.5MM in all three grooves, not 1/16,1/16, 3/16

As has been mentioned....... with the heads having 2.25 intake valves, and not knowing if oversized seats have been installed to facilitate that...... they could be a big fan of worms.
Buying used race stuff is risky at best...... throw unknown stage 6 heads into the mix...... and the risk factor def goes up.
Perhaps there is documentation of exactly what’s been done to the heads buy the shop that did them. They might be really nice set of heads........ but they also might have intake seats about ready to fall out.
11’s out of a Charger? That’s just a flat top 440 with a decent cam, e street heads, an rpm intake, headers, 9.5 converter and 3.91/4.10 gears.
