I went with the Forged Scat 496 assembly myself. After tons of research and after talking to numerous engine builders, that's ultimately what I decided on. I also went with the internal balance. The guys over at team chevelle are very helpful and really know their stuff when it comes to building streetable metric ton of power! Here is what I've gathered so far for my new build.

291 block on stock bore
Scat H-beam rods
Scat forged crank
Mahle forged 18cc dome pistons
ARP main studs, rod bolts, head studs as well as an ARP engine bolt kit
049 heads with 2.19/1.88 manly SS extreme duty valves. No port work has been done to the heads yet, as I'm still debating on pulling the trigger on a set of AFR 265cc cnc chambered heads.
Comp Cams Stainless Ultra Magnum rockers
Moroso oil pan with windage tray, baffle and scraper
Billet MSD distributor
Holley billet mechanical fuel pump, 170GPH internally regulated.
ATI internal balance super dampner
Edelbrock rpm air gap
Holley 950hp billet carb

I haven't ordered a cam yet, as I'm still trying to decide whether or not to run the 049 heads or come up with the money for the AFR heads. Either way, I'm going to run a Straub billet hydraulic roller matched to which ever heads I use. I'm going a step further with the lifters and going to have my block machined for the .920 lifters. They are larger and stronger than the stock sized lifters. Plus doing this will allow the machine shop to properly size the lifter bores as well as square them up with the block. Overkill? Yes and no. All three of the big name engine builders I talked to about this build all agreed that it would result in more power and reliability. How much power is unknown, however one builder threw out the 15-20hp number. The extra power is strictly coming from proper alignment of the lifter bores as well as properly matched and sized to the lifters. In short, its relieving a lot of friction. I've been accumulating parts and researching different builders and ideas for a year and half now on what the ultimate 496 combo is. If you'd like any help or information that I've been able to gather, just let me know!
