Okay so i have a huge problem i want ARP exhaust manifold studs but according to arp they dont make them that short with that thread pitch!! this is what i have gatherd so far
they are 2.25 inches long with M10x1.25 thread pitch. but i called ARP's special order department they said they have 2 inch and 2.5inch definately not what im looking for but could work. the only reason i couldnt buy them is because the rep also told me that there is one more number for thread pitch it was something like 361? or 362? he said one is like a tighter fit and one is a looser fit what does this mean? he said if i choose the wrong size it might only go in half way then stop. it is for my head so i dont want to damage it.
WHY DOES ARP NOT MAKE THEM!!!
please help. or give me any possible alternatives for a grade 8 or stronger stud as these are a pain to remove when the engine is in the car thanks.
