340 Stroker: experiences with parts

I was able to buy a 340 engine, which I would like to build up for my Duster over the winter
The idea is a nice stroker, roadworthy
I've thought about it a lot, but there are so many brands and parts that the more I research and search, the more I lose track
Starting point:
1970 Plymouth Duster
904 automatic, Stock
8.75 rear end, 2.94 with position
Wheels: 15x8, 255 60 R15
Front: TB 1.08, Hellwig Sway Bar, Billstein Shocks
Rear: Hotchkis Leaf Spring, Billstein Shocks
340 of 1971, J Heads
HP exhaust manifold from the 340 (I know that headers would be better, but here in Switzerland it is not easy to check them, which is why the HP cast manifolds are tight)
Disc brakes with brake booster

Which stroker kit manufacturer do you recommend? You read a lot of good things about Scat, less about Eagle, but I can't judge.

The Heads: Does it make sense to keep the J Heads, just port them and reuse them? Or go on aluminum heads?
Edelbrock, Trickflow etc. there are so many Or diw Indy Steel Heads?

Camshaft?
Converter from the 904 stock or another? If yes, how much stable?

I currently have a Ofenhauser spider on the engine, will I continue to use it?

What carburetor? So size? Type? Etc.

roller rockers? yes or no?

Lots of questions, I know, but I can hardly see through them at the moment, so it would be cool if you could show me the right one

The goal is a roadworthy engine, great torque out at the bottom, no high-revving screamer

Or does anyone even have a "shopping list"?
