    Plan to install my heads later this weekend on my 348 motor. The manual specifies a Molikote grease product. Is this simply an anti-friction lubricant or is there another task the product performs? Is a quality anti-seize product suitable? Thanks for the help.

    Wish I could answer your question with confidence. I think the reason they want you to use the grease is to obtain the proper torque. So I would suspect that any good engine assembly lube will due. Give ARP a call you can get the number from their website http://www.arp-bolts.com/ They also have a tech info page that sould be of some help.

    Ernie, thank you. I suspected the Molicote is for assembly.
    Another question. As you are well aware, the torque spec calls for 60Nm, then a 90 degree turn of the nut for final torque. This is similar to GM’s current head torque spec. GM also requires replacement of the head studs after use. GM does not recommend use of the old studs because they are already “stretched”.
    The Ferrari workshop manual does not reference this point. Should the studs be replaced?

    On theory yes replace head studs if you take the head off. In reality it makes little practical difference.
