Hi all had me 3 door cosworth on the rollers last week and it made 328bhp & 347 ibft of torque. The thing is my head gasket started to weep oil and water so i have taken the head off, had it skimmed new guides etc and the guy at CTM said it had never been skimmed before. It was on stretch bolts before, and now i am coming to put it back together, DO I USE ARP STUD KIT or STRETCH BOLTS, the other thing is do i use the grease that comes with the ARP kit or a light oil.
many thanks PAZ

 

I would have thought STD ford bolts with a decent gasket at 330bhp will be fine

 

Listen to Charlie or Nick sure he will tell you what you want for your spec

 

Also if going ARP DONT use the kit go for thr full long studs

 

3 door is 2wd so can't long stud.
I would use ARP, made UP to a specification, not DOWN to a price like ford bits!!

Go ARP with a decent head gasket

 

what should these be torqed to as opposed to the original stretch bolts?

 

long self tapping screws are good

 

std ford bolts commetic headgastket ( my car is running 330+ for a few years on this combination )

 

i use ARP nut and stud kit and my car has around 380hp and i have had on problem what so evey

 

 

thanks all i will go down the arp route me thinks

 

Stage 1) 20-25Nm
Stage 2) 45-50Nm
Stage 3) Rotate further 170-180
