Well I only had the 317s on because I was going to go turbo until I saw the glory of all motor setups. but right now I'm looking at a set of 241 or 243s but my budget is a little tight and payday is 2 weeks away so I can afford the 241s but I want to set it up right

Some ported 243's from AI or even 241's with [B]1.7[B] rockers and some springs good to .650 (PRC duals would fit the bill) Either way that's a really aggressive cam and it will feel like a dog down low with 317's. 5.3L heads would be better to get the compression up.
The 1.8 rocker would give you a lift of .648". Even with a 1.7 rocker you will need to check PTV clearances.

If I recall correctly the Megadeath cam was cut to be an all out stock longblock cam. If you are going to run that cam keep your 1.7 rockers, don't use 317 heads, and get some 3.73s and a tune.

Going to take a pretty big cam with an LS6 intake, and a stock set of 243's even ported 243's to make that and still be as street-able as a smaller cam.
All depends on the port work really, if it's a set of AI heads or TEA heads then yea I can see it doing that with a street-able cam.
I would also consider 4.10's with the 6 speed unless you have to keep the 3.73's.
1.8's will make the lift even higher, the duration higher and ramp ratio higher all things that I bet those springs can't control.
We have a great valve spring package if you're interested. Zero failure rate with the springs I'd like to see you use.
