So I'm looking to keep the heads at the same combustion chamber CC, put better flowing heads on and a better cam. Hence why I was hoping someone with no part number of my cam and give me specs. So I can compare.

And then there is the weight savings from going to aluminum. 100 lbs off the ass has to help in its self. 292's are ass heavy.

What BillK is trying to tell you, is that you can get away with a higher compression ratio and still be safe with the aluminum heads. One attribute being they dissipate heat better.
Research it a while.
And not sure you're going to find anyone on here with the specs to the cam number you've posted.
The typical response to all the 6.2 upgrade threads is; Leave it alone.
Not many people fool with the 6.2's other than just run them.
Mostly because they pretty much need a complete redo so to speak.

BTW, what do you plan to do tune wise, exhaust, if and after you do swap heads and cams?

Link to one of the best 6.2 builds on here, probably the only one. LOL
Even if you're not going that whole route, It's informative.
