a. Get another head
b. clearance the head to fit the pistons by flycutting and or hand grinding.
(expensive and compression will be high)
c. replace the pistons with flatops
d. if the R16 pistons aren't cracked (they often are) , pull them out put them
in a lathe and make them flattops. (Easy compared to the head machining).
works fine.

Subject: R1600 Head Stuff
Hi,
I just had the head from my 1600 milled. It mic-ed to 3.175. What is the
minimum?
I assume this is below tolerance, because I put it back on, without the
gasket, and finger tightened the
head bolts, and the pistons are making contact, when I manually crank it.
Is there anything I can do to save this head? It's in pretty good shape,
minimal pitting, valves look good.
What about a shim, or double gasket?
Thanks for your ideas - Robert Long - 67.5 headless 1600 - Albuquerque, NM
