Cam advise for stock lq4

Cam advise for stock lq4
We swapped a stock lq4 into our 02 ws6.
So it's a stock lq4, ls6 intake, 1-7/8 headers to 3" out the rear.
Stock torque converter and 3.73 gears and an 60e tranny.
What's the best cam for this lq4 with stock converter?
Might one day if we find a good deal swap 243s on it also.
Springs will also be swapped for the cam

LQ4 is a bit down on compression so the 243s or a quick mill on the stock heads will wake things up a good bit I think and possibly change your cam selection a little. That being said, a stall convertor could gain you as much or more than a cam though the tiny LQ4 cam surely deserves replacement.
Have you budgeted for aftermarket valve springs and associated items or are you looking for more of a budget-friendly drop-in?
Food for thought:

Advice is free so I'd recommend calling a custom cam mfg and getting their take. If they don't have the perfect shelf cam they should be able to grind something just for you for about the same price in short order.

Yeah we will swap out springs for the cam but money is limited when it comes on which route to go first on mods... I'm sure we'll do a full tune first then the route listed below as money is slowly building up for his mods. Bad thing about a torque convertor is how much longer will the 60e last before a rebuild is needed and then possibly mess up the torque convertor if trash gets in it. A tc may be last unless we find a good deal on one. Or should we go a different route on the list of money spent on mods below.

I am not an auto guy so I'll pause until someone with more 4L60 experience can give some feedback on those miles on that transmission. What I do know is that the risk with a stall is that stall=slippage=heat and heat will kill any transmission, new or old. So upgrading the cooler would be important. This is usually not expensive.

IMO. you would have a difficult time beating the GT2-3 cam from Lingenfelter
Pop some GM blue LS3 springs in with a new LS2 chain and shim the bypass spring in the oil pump, replace push rods and oil pump if funds allow or run what you got
It'll still drive nice have great low end torque and be stock converter friendly
Then get the car tuned

Hey LS1 pwrd NOVA,
I would like to offer you a couple options:
First, we have a great camshaft we designed just for guys who want to keep their stock stall converter. It is what I like to call a "no sacrifice" camshaft. It has more power than a stock LS1 camshaft everywhere in the powerband, yet it maintains like-stock or better than stock drivability. You can't lose if you are upgrading from stock with this cam. Check it out:

If you do decide to install a mild stall conveter in the 2800-3000 range, have a look at our Titan III. It will have a mild performance idle and great daily driver manners while still making great power:

If the car is more of a hotrod and you want a "lopey" hotrod style idle, then you might like a 3500 RPM area stall converter and our Titan V camshaft. This camshaft has the hotrod personality, but still maintains good drivability for a serious street performance camshaft:

We can also set you up with matching valve springs, pushrods, timing set or anything else you might need to complete your swap.

I would have no basis of test info other than the fact that lobe design and valve control is a constant process of improving through design and testing. I can say that virtually every single person to have run the GT2-3 had positive feedback regarding the power and drivability

I ask because that cam was designed in the era before single springs were available to handle very high lifts. Also it is designed for manifolds and not headers- the negative duration at .050 is not too far from the stock LS6 camshaft so it does not gain as much with long tube headers compared to other designs with the same powerband.
