If you're going to do a stroker LS please make sure and talk to Kurt Urban about using offset pin pistons. Dramatically quieter on the stroker motors. The LS have an issue with a longer stroke in that the piston goes so far out the bottom of the cylinder, it rocks in the bore when the piston changes directions. I put in the offset pin pistons as per his advice (bought everything from him) and the engine was completely quiet even when dead cold. The previous piston was not, had the typical piston slap issue which with my quiet exhaust drove me nuts.
Once you pick an engine builder and you should trust them if you do, take their advice. The best engine builders have parts they trust due to tear downs and inspections for freshen ups.
I'm certainly not saying to put your head in the sand and let them run with it. I'm talking about the meat and potatos. (Crank, rods, pistons, rings, valve springs, push rods, etc)
Had dealings with Casey Wegner and Kurt Urban. Great guys to deal with. They have that quiet confidence. No ego driven talk. Very knowledgable about LS stuff. Worth a call before swiping the card.
Not taking anything away from other talented builders here, just my experience. Thanks.
