is there any way of telling a engine has been long studded or they are just arp stud and nuts when the head is bolted down??
is there a part number on the nuts or something??

 

well, as a start, look and see if it has 6 studs and 4 std head bolts....most people only do 6 long studs

not always though you do get 10 long studs sometimes, im sure you need to mod the water pump for the, so you may spot it that way....

 

no there's 10 studs, supposed to be a mountune block. what's the mod to look for??

 

any 1??

 

Have you any pics? maybe someone will be know more then???

 

Take off the water pump, if it's 10 long studded you will see the front 2 through the water pump hole.

 

cheers mate

 

Hi if properly long studded you will need a very slim fit 17mm socket to undo! ARP have no issues to undo or fit!

 

Most long studs have an 18mm nut So you may have to hammer the 17mm socket on !!

 

why would that be if arp's are 17mm??

 

are arp's 17mm and long studs 18mm nut's then?

 

Not sure what ARP's are as I never use them. As said most UK supplied (Mountune etc) long studs have 18mm headed nuts, the type of long stud that I use does have a 17mm head but even though these are much better they not widly used.

 

you have pm martin

 

i use martins!


very good aswell

 

think the 17mm long studs are fairly new ,martin and ava are the only ones ive heard useing/supplying them,with good results also

 

the 18mm 1's are a pain in the tits, took me ages to grind a socket to fit then it just cracked, ended up borrowing a socket off andy gallacher, added nearly 4 hours onto the job,
wasn't very happy at all that day

 

sorry yes 18mm i got my nuts machined to 17mm.

 

ive been there mate,try the early 3-door/early saph head the holes are even smaller and the head needs machined
