For a turbo setup that would be great to have ported heads but still the LS6 cam as the turbo helps to push in air through the better flowing heads.
But on an N/A setup the extra flow of the heads will be wasted with a small cam like that so it's almost not going to do much for you. I agree that just milling the heads, maybe even doing a nice valve job will be all that the LS6 cam will need. Anymore and it won't have the oomph to take advantage of all that flow.

I dont know about that. Ive seen dyno sheets of cnc ls6 heads with the stock LS1 cam and the car picked up good power. I think it was AI that posted a step by step dyno sheet of a bolt on car then their with heads with the stock cam.

I agree that ported heads are going to wake the car up and help make some more power, but why not add in a really good cam to go with the heads? I guess I can see doing a cam only swap, but not a heads only swap. Might as well do both at the same time and double the horsepower output that you'd get by doing a heads only swap. Kind of like eating cereal without milk. Can you do it; sure. Does it taste better with milk; yep.

Because I do not want a cam or need one. Thats like saying why waste the money on a small cam and not do a big one, its not for everyone. Or why waste the money just doing a cam and not heads. Or the way I see it, why bother doing a cam only setup at all when an ls6 will make just as much if not more power/torque, drive better and be more efficient with stock parts. I cant see spending the money on something slightly bigger than what i have to get another 20hp then have to say I have a heads cam ls6 when i can put stock ported heads on it make atleast 415 go bottom 11s and be able to say I have a stock cam motor with ported stock heads

Livernois Stage 1+ heads and LS6 camshaft This is exactly the type of build these heads are for. It's a nice set of heads for a person not running a big camshaft.(.575" max lift) LS6 camshaft is .550" If a person decides down the road to go to more camshaft this is a spring lock retainer kit away from being our LS Stage 2 head! These are a fantastic buy.

I did heads with the stock LS1 baby cam once. Picked up 30 rwhp. But this was 853s to badass ported 799s from Advanced Induction.
I then added a 226/230 cam and picked up 66 rwhp lol.
Since you already have 243s, I don't think you'll gain more than 20 rwhp, even with the bigger ls6 cam. I agree with redtan though, just mill your own heads and put them right back on. Get a .040" cometic too. All the gains you're going to get are from the compression, so maximize it.
