[Roadsters] R16 head thickness

[MH]

Perfect candidate for dished pistons CR wise. Dished pistons are somewhere 
between 5-6 cc's, standard bore is about 1cc per .007" of swept volume. Of 
course with the geometry of the combustion chamber varying with depth, you 
would do well to cc the chambers anyway, just so you can really dial it in.

Also, there are now thicker head gaskets available at www.datsunparts.com, 
they're about 40-50 thousandths thicker than the stock gaskets. Just the 
thing for thin heads, check it out.
