Can Anyone tell me what studs or bolts to buy, or what size they are, just for the intake manifold to the head.

First of all, do you own a tape measure? You'll have to figure out the kength you want on your own. Most of us buy cars/engines that have all the bolts with them. Those of us that don't have the knowledge to figure it out...

The intake manifold bolts (KA, SR, CA, pretty much ANY other nissan EVER produced) are 8mm x 1.25mm...

take a pencil and stick it in the hole until it stops then mark the pencil.

Measure the length of the pencil from the end to the mark.

There's the length you need.

For the thread pitch, go to the hardware store and buy some bolts of different diameters/pitches.

SLOWLY and Carefully try to thread them in. If they bind or don't engage try a different pitch.

For the exhaust I would suggest these:

I have them on my rb25 and I liked them.
