You're wasting your time installing head studs with stock connecting rods in it. A tune that will keep the rods inside won't lift the head either.

But, to answer your question, yes, just use an OEM gasket. And get the head resurfaced.

It's pretty easy to valve springs and retainers without pulling the head. I've done several. You use compressed air or the rope method to hold the valve in place, works very well. Theres a few DIY threads on it. This is the tool to use..

Just changed valve springs and retainers with head still on a couple of days ago without using air or rope. Valves won't fall on cylinders 1 and 4 on tdc. Just rotate engine to do cylinders 2 and 3.

I feel this is safest way for first timers. This is what I did because if any valve falls in, then you will have to remove the head. Drawback with this is it is more work and will need timing to be reset unless you mark your timing belt and each sprocket to take away any guess work (crank pulley always seen to be off by 1/2 tooth, which is VERY annoying!!).

There's marks for all the pulleys. No need to mark the belt to the pulley. Just have to set the crank back a smidge to account for the tensioner taking up slack.
