747pwr Member 68 Member For: 14y 2m 6d Gender: Male Posted 28/12/13 02:24 PM Share Posted 28/12/13 02:24 PM Hi guysJust wondering how difficult it is to replace the factory head bolts with head studs while the motor is still in the car, does the valve train need to be removed or can I simply remove/replace one at a time and then torque them all down or Do I need to remove the head to make sure all the stud lengths come out the block the same?( am away from the vehicle atm or I would just remove the rocker cover and have a look.)Cheers Link to comment https://www.fordxr6turbo.com/forum/topic/87158-replacing-head-bolts-with-head-studs/ Share on other sites More sharing options...

I think it is with the 1/2 studs that needs the head holes to be drilled to 13mm. But don't quote my sizes.

Surely other people have upgraded to head studs without taking the head off and while the engine is still in the car.
