Have a go at rewording this..

I am not sure what you are asking....normal manifold exhaust bolts are 14mm off the top of my head....as far as the anf sizing goes.............

I would suggest going to the wreckers and getting some bolts out of any out V6.....U should be pretty much right........

I dont know if this is what you are asking.....they pretty much put your old bolts back in when you change to extractors or headers....No special bolts required....

You could use your old ones, or take one of the old ones out & get the size of it and replace with new ones.

Thanks guys!

Just reuse the old ones, no need to fit new bolts when fitting extractors. Just make sure you use new gaskets and an O2 sensor safe sealant.

No worries, just wanted to make it look a little better with some new shiny bolts to go with the freshly painted pacemakers thats all.

Get yours zinc coated maybe? Or just buff the heads up on a wire wheel.

Or soak them in Coke overnight, works on money, not sure if it would work on a bolt though.

5/16 UNC. The studs are 5/16 UNC on the block side & 5/16 UNF on the nut side.

ARP 3800 header bolts are very nice.

Got mine from Intense Racing but they must be on ebay too.

The stainless standard bolt type, or the studs with nuts?

I'm about to do my head gasket when the kit arrives. Went to WD40 the manifold bolts ahead of time and noticed the left front manifold bolt is snapped already. Not sure why, just acquired the car with 360k on the dial.

I have seen a youtube video of a dude recommending not to remove the bolts as you go, but rather, loosen them free, then tighten them back in again, until they are all broken loose. Otherwise you can put a lot of extra pressure on the last one or 2 on that bank. The guy said a lot of people snap the last one or two bolts because of not keeping the manifold flush with the head.
