To stroke or not?

if I want to use that crank, could I use my current gen 4 rods and get pistons to accommodate the stroker crank and still use the gen 4 rods?
thinking I’ll run the above crank, and these pistons

that’ll allow me to use my current gen 4 rods

I can't speak for Summit's cranks but usually the stroker cranks have the counterweights cam cut for a 6.125" rod, so be sure to check the clearance between the counterweight and the underside of the piston pin boss at bottom dead center. The bottom of the cylinders will most likely need to be clearanced as well.

I want some opinions on this, for my setup, should I stick with the 317 heads and get them milled a little to bump the compression or should I go for the 241 heads? The heads I pulled off this motor are super clean.

You will make more power with the L92/LS3 top end without raising your compression.

Going back to your comment about raising compression.
I would avoid that due to the vehicle being your daily, the big tires, all the towing, and trips you make. This is not your weekend racing car. Filling up with 93 octane gets expensive. I know, because I have 3 vehicles that run on it. I would love a daily that runs on 87 octane especially with the way prices are currently.
Personally, I would have the highest compression that could still be ran on a 87 octane tune. I just watched a YouTube video that made me consider this.
With a 6.0, L92/LS3 topend, cold air intake, cam, full exhaust, and 87 octane tune you should be over 400rwhp easily with good driving manners, power, and a reasonable cost to fill up.
The LS3 in the video only has cold air intake, headers, and tune on 87 octane and made 411rwhp and 420 rwhp. The engine has a compression of 10.4 : 1 if it's a L99/LS3.
Let's compare what I'm suggesting for you to this LS3/L99.
The difference between a 6.0 and 6.2 block is that the LS3 has an extra 12 cubic inches and/or .2L of displacement which is not much.
With a 6.0, L92/LS3 topend, cold air intake, cam, full exhaust, and 87 octane tune you should be at the same place in power if not more compared to the Camaro in the video.

Curious which CCW cranks ER would not consider (due to quality based on comment in another thread) compared to a non ccw crank of same price or cheaper.

Reason being? Erik and SAM used to run it in there stuff... Fastest 408 na Lq I know of crank was a Eagle.
CCW is good for and With Rpm... If you've gotta question a Purchase or material...👎
Me I'll go research and post on The Question of, on here and the other 2 Forums. Besides the first thing of a PM with the Part in question.
TSP has a CCW crank for $1k...good Balance + it's Forged what's the Problem? If we aren't adding 40psi I'd think we're Good...cranks Just don't Break and @ $1000.oo seems like a Good idea Vs the 700 dollar regular forged steel Crank.
If you want the Best CCW crank there's only a few Names...

4.250 CCW vs 4.250 regular both going to 8700 rpm ...CCW wins
Greg Good Build with a 4.250 crank and it having problems...Erik answered I believe...

Chevelle You can't Let everyone Know I can give a Basic Informative Answer...
It does make a Person....Think.
There's Something's I ask And never get a Answer...then I have to think about it... 🤯
It's generally a Common Sense answer.

The Avg guy Doesn't need 1...but if you're getting them @ $1000.oo why Not vs a Regular Callies or K1 crank.

Biggest benefit for CCW Crank is from 7000+RPM NA,
If not spinning 7500-8000 RPM+ NA or BIG Boost, may be hard to justify.
Kinda like the Flat Plane Crank as well.

Also my Mistake....
TSP Sells a CCW crank @ $1k not they Make and sell a CCW crank..
