Personally when we are rebuilding a motor here at the shop we order a gasket kit and replace all gaskets. Its better to have piece of mind when using new so you don't have to worry about any leaks. We typically use cometic, its a good quality set of gaskets and not too hard on the wallet. I'm glad to hear your going to go ahead with a swap. With the overheating issues you had with your previous motor overheating I would have been concerned with the block/cylinders being warped from the heat.

Throttle plate sticking?

The clunking sound, do you hear it all the time while accelerating or just during shifts? How do your trans mounts and pitch mount look? If somethings rocking it could cause the sound youre hearing.

How old are the engine mounts? That creaking sound could be your brakes

Congrats on the purchase! Have pics?
