Cam & head upgrade 360 mag

I know a lot of my power is lurking in them gears, I am doing the gear swap before I change the cam and heads, because I know I might be more then satisfied with the way it performs.
I just know myself and once I do the gears I'll want more out of it.
How much more is yet to be determined, I've considered a stroker kit, but I don't want to spend that much money, specially when I can get quite a bit more power from a bigger camshaft and better flowing heads.
And a new camshaft and the iron ram Eq heads isn't really that expensive.
