i run a cometic 3 layer gasket just now with no issuesalthough i did first time round with them

doesanyone run/rate the 4 layer cometic?

also i long studded my 200 block with mountune 6
but just incase theres issues with them when i remove head

are arp ones ok to go for stick to mouuntune?

i just remember having 4 arp head bolts to go in place of the standard ones when building engine but was advised against them due to cracking block/head cant remember

any views appreciated

 

From what i have heard there are better long studs than the mountune ones, as they seem to stretch at different rates.

 

called what neil?

 

Ask alan he got mine through a contact of Mike R i think.
Im sure Martin said he can get good studs aswell.

 

Col when using 6 long studs,you are ment to use standard used head bolts in the other 4 holes

cheeRS stu

 

i did but used brand new ones stu

surely once they ve been stretched you only get once shot at them no?

 

mine is decked n skimmed and i use a mountune 3 layer steel gasket.....6 long stud all supplied by Ahmed,the 4 other bolts are old used jobbies........

 

ARP make fasteners/studs/bolts for a living, they don't make rubbish, but it is rubbish to think that a stud is ever going to be strong enough to break a block, if the block were that weak just starting it up would blow it apart with compression.
Idiots who try to force studs, bolts into holes are the likely cause of block cracking, some don't even tap the holes to get congealed oil/crap out before rebuilds.

You use sh bolts in the corners,as they have already stretched,and shouldnt stretch any more,there fore stopping the head from lifting at corners,or so im tld any way

Mountune one are fine until 450 ATW ish col.

Speak to Alan or Mike if you want something better

Not sure what they are called but they come from Scandanavia somewhere.
