On our magna's the redline is 6,000 RPM give or take a bit for late model 3rd Gen's i don't know. I know on my 2nd gen V6 it'll go to 6,200RPM then hit cutout.
My question is why is it set there? 6,000RPM is a lot i know but what is holding it back from reving more??? If i was to high flow the heads, cams etc and install a piggy-back programable ecu and muck around with redline, could the bottom end and pistons etc take the higher revs if more power can be gained at a higher rev, say 6,750RPM??? Our cars are not really designed to be the fastest, most powerful cars on the road, therefore they are retarded and detuned for fuel economy, longer life, woteva
Could anything be gained or would this just cause un nessesary engine wear

Might bust a conrod or spin a bearing... Don't forget that revving higher does not produce any more power if the torque drops off substantially, as you are passing the limits of the engine design.

But its still good fun, although something just doesn't sound right at 7000 rpm...hhmmmmmm.

Cam design and making the bore/stroke more undersquare will increase your redline, but that will also mean that low end will suffer.

Redline isnt really worth worrying about, the work you want to do will increase the power range substantially and you'll have a relatively similar redline.

I dont think there would be much point in increasing it unless you completely redesigned the motor to use it, which is big work/big money. But if that's what you're thinking of...go for it.

i have got my mums tf to rev at just under 7 grand a few times, dont know if it does any good for the engine though
