ARP doesn't list as having flywheel bolts specifically for an H series. Their catalog only lists them for D and B series. Are H series flywheel bolts also 12mm x 1.0? If anyone out there is using ARP flywheel bolts on an H22 and can fill me in on what you ordered that would be great!
Why bother? Just use stock. There's no reason to use something stronger. That's just my opinion. However, to answer your question, yes, the stock flywheel bolts are M12x1.0. I would definitely compare a B/D series bolt to an H series before trying to use them. The lengths, shoulder diameter, etc could be different.
Before I get flamed, let me say this. David warped an entire Fidanza flywheel and Exedy pressure plate with a horrible mis-shift. The flywheel bolts looked perfect.
The surface of the flywheel and pressure plate was flat, but the "core" of the flywheel had shifted. It was enough that a stock PP would not bolt up to it because the dowels were in the wrong place! Didn't stretch the flywheel bolts or anything.
