arp or standard head bolts
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

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!!
