looking for a truck cam ok so building for fuel econimy is out the window so looking for a truck cam for daily driver may give a little power boost. like a stage 2 but i don't wont to change the converter. much less just replace the cam that's in there. i im using flat top pistons, it is going in a 2002 avalanche. any ideas i can research

We're going to need a lot more info than "I have flat top pistons" and "I'm considering a 'stage 2' cam".
What engine? What heads? What truck is it going into and what will you be doing with it? What is your budget?
My boxed reply is to look at Summit's offerings for truck cams and pick one that will work in your application.

lol that's a oops . ok i have a 5.3 Vortec in an avalanche 2002, everyday driver 300 on the odometer so time for a rebuild. I have 799 and 706 heads available. there are dish pistons in the motor. so 799 heads better flow 2 inch valves is where I was headed. but need to find out what's cheaper, milling the 799 heads or cutting 2-inch valves in the 706 heads. so I was going with flat top pistons with the 799 heads with milling 20 off. then what cam? I'm not building a hotrod but at this point, a better cam might be a good idea. truck cam. I haven't been doing any towing but yea never know. 16-inch tires automatic trans 4x4 and really don't want to get into buying a torque converter..

Read my post in your other thread. Both cams I listed will be very helpful to you. You don't need more than that IF you really want fuel economy.
Plus, as was also said in the other thread, a good tune will really help you.

yes but they need a torque converter dont they? gave up the thought of fuel just deal with it lol so im rebuilding. should i just go stock or make a few small adjustments. torque converter didn't really want to go that fare for a daily driver. have seen some stage one cams.

Absolutely NOT. They idle like stock. Only more radical cams that lope need a converter.
To repeat- NO CONVERTER NEEDED!! You really need to learn more about how different cams behave.
The 2 cams I mention are less duration than some stock cams, but these have more lift and are optimized for making low end torque while improving power everywhere.

On the valve springs, for that cam the LS2/3 beehive springs will be plenty.
With that mild a cam, you could get by with stock pushrods, but the extra insurance of stronger new ones is a good idea.
If you mill the heads and use the thinner head gasket, it is a good idea to measure for correct pushrod length as said above.
