Jon,
I don't know myself, but I'm pretty sure this has been discussed. Have you
searched the the list archives and/or the forums on 311s.org?
Oh, what the heck....searching....searching.....came up with this on
311s.org:
"The minimum thickness for an R head is 3.246"
"The minimum thickness for a U20 head is between 4.528-4.530"
Hope this helps.

Subject: Fw: New and Minimum Head Thickness
Hi All, A quick question for The List with an apology for not saving the
answer earlier.
I'm interested in knowing the thickness of an unshaved head and also what is
considered the minimum head thickness without having to go to additional
measures (gaskets/shims, etc). Looked in my Clymer 'Datsun Sport Car' manual
but can't seem to find it. If it's there, please tell me where.
We're getting to the engine work in my son's project: Car is now in the
body/piant shop. We actually have several heads to pick from and the overall
head thickness is one of the factors that we want to take into consideration
when deciding which head to go with. Feedback from the list would be
appreciated.
Thanks Jon
