[Vwdiesel] 81 Head Bolts

[B & R Decker]

	Perhaps you could just use ARP gas Rabbit head studs. They should
help prevent head gasket problems and they are reusable. 11mm diesel head
studs are available from Race-Ware and I have used them with success. They
are more expensive than the ARP and I would believe even tho ARP doesn't
list 11mm diesel head studs that the ARP Rabbit gas 11mm studs should fit.
I'm going to buy a set of ARP 11mm gas Rabbit studs to use in my 11mm 1.6
block that is getting rebored .5mm over and I am installing a 1.5 crank rods
and pistons. I will then install a turbo and intercooler. I will install
this engine either in my 1981 Rabbit diesel pickup or perhaps in my 1990 Fox
station wagon

Are some of the 11mm heads shorter than others? I can't imagine that is the
case.
