If you can't put in valve springs, then you won't be putting an aftermarket cam in, period.
That's like asking for advice on swimming strokes when you're unwilling to get in the water.
Can't swim much without the wet stuff, can't install an aftermarket cam without the valve springs...

NONE! even the stock cam is really to much for the stock valve springs. You can use any of the GM cams with the LS6 valve spring (not your LS1 springs) but none of the "aftermarket" cams (that I know of) can be used with GM valve springs (the ramp rates are too fast/harsh). Even if you go with a GM cam, I would say go on up to the Comp 918 valve spring. That way you not only git some "overkill" for safety but you are also setup to go up to a larger cam if/when you want to.

Dirty Vegas, as for your cam choices for stock springs, you're SOL.

If you don't believe us, put in a T-Rex with some stock springs. Experience is the best teacher.
Don't say we didn't warn you though.
There are a few cams you could swap into your '99 w/ stock springs. Here's the list:
Stock '98 cam
Stock '00 cam
Stock '01 cam
Stock '02 cam (I can sell you one of these if you would like, $75 shipped).
Good luck.

Someone told me to keep the stock pushrods as a 'fuse' for the motor...that if I got aftermarket pushrods that were stronger, I would risk damaging the valves, but if I kept the stock pushrods in, they would go first and it would be cheap to replace. Is this sound thinking?
