NO , Main studs are for the MAIN CAPS on the CRANKSHAFT...
You'll still want the studs for the 2.4 head/block .

Im prity sure your going to want to get the 2.3 head studs if your doing the 2.3 head swap. The 2.4 studs are 8mm vs the 10mm 2.3. So if you have the 8mm studs with a 10mm hole head. That potentially gives the head room to walk around on the block during heat cycling.
Putting the 2.3 studs in the 2.4 block is going to take some maching and re taping of the block to get them to fit though. Another option would be to use some kind of bushing on the 2.4 studs to make up the extra 2mm.

JBP is the only place I know of that sells them...
Someone had a part number (black sunfire, chrome rims), but I think the ones he got were too short or something
