Default Help me make a build a 455ho

I have a 1972 yb code 455ho. Its the original engine to a 72 gto coupled to a th400. I want it to retain the factory heads, and appear from the outside to be stock, even valve covers, except for the fact it will have black long tube headers. It will have a full 3", rear exit exhaust.
My gut says put a modern rotating assembly instead of reconditioning the rods, and using a oem crank. Stroker kits worth it? I would like to hear whats good in 2021. Eagle, Butler?? I need to Pick out roller cam that will work with the iron heads and oem aluminum intake. Head wise, i am looking to leave them mostly alone except a clean up cut, valve job, and recommended springs retainers. Perhaps some crower enduro rockers. Would prefer to keep it on premium pump gas if i can.
Also an opinion on the converter. Rear gear will be a 12 bolt, somewhere around a 3.42 gear. 27" tall tire. This car will be used as an aggressive weekend cruiser. Maybe 2000 miles per season. I want it to straight up snap your neck. Chime in if you have any opinions. This kinda is a blank canvas. I am willing to spend some coin. This is a one time deal. I want it to run. Thanks
