Everything ive found the rectangular heads like split duration and lift.... If youbwanna stay with stock stall you may wanna look into vvt cam or something custom specd for it....

Man I sure wish I would've known I had vvt. The vvt cam and phaser would have been nice. I see tsp makes a vvt delete kit for about $120. If the cam I have sitting in my garage will work, it'd be nice to get the kit and throw in the cam.
Yeah that would be great with a cathedral port headed engine.... I had a 222/224 .566/.568 112 and it ran ok but left ALOT on the table!!!
What would be the result of running it with my 823 heads? If I can get away with throwing it in and running it without it's full potential, I'd be fine with that until I can free up some funds for a nice set of cathedral port heads.
And also, I had planned on using my stock lifters. I see mixed opinions on doing this. I see some say yes, some say no way in hell. My reasoning is to avoid pulling the heads until I man up and buy a set of heads so I can replace lifters and heads all at once rather than pulling the heads twice. My question is will my 100k mile stock lifters be alright with this cam, or at least until I do a head swap and replace them then?
You will severely lack low end, it will be great up top but leave a lot to be desired. Swapping heads is going to require an intake as well, if i were in your shoes in would see if you could return the cam and exchange it for something more suited to the engine with a higher stall or maybe even a vvt cam, unless you plan on running boost later on down the road.... Another word of advice, when you pull the cam check the bearings real good... The gen iv are known for cam bearings going out, and theres even a bulletin about the cam locator pin shearing off in the phaser..... I have a 6.0 with 823 heads in my 99 im now running a btr stage 2 ls3 cam in now which has 225/238 612/586 113 i havent been able to get the truck out of my buddys backyard due to the excess rain weve had the last few weeks and fact i think i may have goofed on a spring or two, but im going to go get it out on the road tomorrow and see how it does real quick.... Sounds a lot more solid than the old cam did if that makes sense... And thats just at idle!!

Ehhhh thats an iffy chance.. if it were an older gen 3 engine id say run it, but its iffy as to whether the lifters are still in good shape or not... Im assuming you have an l96 which would be same as i have for my yukon at machine shop right now, hopefully hear back on it this week.. But heres what one of my lifters looked like.....
There was no evidence of it on the cam that i could tell.... But make sure if you decide to run it to use dowels to hold the lifters up while you swap them and if anything on the cam lobes looks suspicious be prepared to pull heads....

Gotcha, I think I might look into a vvt cam being as I do like the concept and I plan on staying n/a. I was actually looking at a btr cam but I liked the cam package that tsp offered. I had actually ordered the 224/224 114 lsa but I decided to sacrifice a little power for a more aggressive idle and go with the 220r so I could go with the 112 lsa and also keep my stock converter. The more I think about it the more I feel like I just need get a stall and go with a bigger cam

Well that's assuring because that was my plan, just inspect the old cam and go from there. Thanks a lot by the way man, you've been a huge help! I feel a lot better rather than my truck being torn apart and not knowing what to do next
