Hi Barry,
With my 100 I went with a new alloy head. When its painted this head is very
hardly distinguishable from an original head (at least from the outside). I
keep the good cast iron original one in my shelf in the loft.
No thicker version was made for the BN2. So you only have the alternative of
an alloy head instead of the cast iron original one.
The 960 head was introduced with the early 3000 MK1s and is common to all
3000s up.

Hi Josef, So what model is your recommendation for a "thicker"
cylinder head for a 1956 100M. I am in the process of searching/ buying  an M
and wondered whether I should buy the alloy version from Denis Welch to avoid
the hairline cracks of the "thinner" version?
 From your note to Chris, do I understand the 960 was just for the BJ8? Was
there a thicker version made for the BN2? Thank you for your help with this.
