i had a feeling it would come right out, i really dont think threads bound up or anything like that from the pic you posted.
i wouldnt touch the other bolts and remove the preload from the head gasket. replace that bolt, work up slowly to the torque value and slap the rest of that bitch back together. do you have a tap you can run down in there just to make sure threads are clean? drop it in there and use a 1/4" 12 point socket that fits the square end of the tap, and an extension. i hope it goes without saying: make sure you oil the head bolt heads and threads.

I'm worried about cross threading if I tap it but I will probably do that.
I think I'm going to buy a set of head bolts. If I dont want to remove preload can I remove and retorque each bolt one at a time?
Need to go buy a magnet and a tap.

it did break in a "perfect way"
unless you are complete tool, thats going to be hard to do. you have the whole head bolt bore to align the tap. just take your time and if it feels like you are cutting threads, stop.
upon further consideration, if you dont already have that tap size and you are going to go buy one anyway, get a chaser, not a tap. most jap threads are tighter than most "over the counter taps", and youll end up with a lower thread percentage if you run a "regular tap" through it, this is an assumption on my parts, not fact.
get a chase, vatozone rents em. just make sure the hex head drive will fit in the hole.
proabably a good idea, but i really dont know, i could go either way on this one. one side of me says, if the current bolts are already torqued and are working why **** with em?
but if that bolt broke maybe a few more arnt far behind. ive never replaced one at a time to save a head gasket, but i dont see why it wouldnt work, especially if you replace them in the same order you torque the bolts.

Can't find any bolt sets local, so I think amazon is the cheapest option so far:
1 day shipping and it will be here Monday morning.
I still need to confirm 1.8 vs 1.6 bolts.

this is funny
VR number you posted listed as 1.8 only for miata, but 1.6 fitment on the 323.

Ok, if that is listed as 90-05, then the set that is listed for a 1.8 would fit. I think I'm going to get the amazon ones if I can't find something locally.

im going to guess that they fit 90-05 and anything saying only 1.8 fitment is a mistake. if they come up for the 1.6 323, then id say theyre the same. this isnt proof though, still conjecture. call your local dealer and see if the oem is the same part number or if they were both superseded to a new number.

Amazon order canceled. I will find out a way to get to Portland and get some from Josh.
So instead today I will put the cams back in, intake manifold. I need to resbond the inconel studs, switch springs, etc, etc.
