A deep well 14mm and you'll be good.

You guys are making some of this more tough than it needs to be.

Use one of your old head bolts grind 3 or 4 vertical slots in the bolt (Dremel tool cutter works well) and clean off any burrs. It can work better than a tap because: It is softer and wont remove too much metal; aswell as not being tapered it will clean out to the bottom of the hole.

Done a bit of research Andy, It seems the extra stud length is not unusual for some reason. The threads are 12mm x 1.25 pitch.

Are you using molly?????

This seems to be more rough for you than it should be.

well the head is on now and torqued to 82.
yes used molly lube only a little though. i reckon of could of torqued them to 95 without feeling to nervous but i chickened out at 82. pleased the head is on though.

iwas just about to attach the plenum manifold but i found a swich/valve looking thing that i unbolted not sure where from think it was either under the injector rail or under the plenum maqnifold ill post a picture of it to show you guys what it looks like.
