842 BBC cylinder head ID.
 

Can anyone fill me in on the subtleties of this head?? Do the production heads differ greatly from the SR's?? Some photos would be nice. I tried the search function, but came up empty.

Thanks in advance. https://www.yenko.net/ubbthreads/imag...mlins/flag.gif

The originals have plugs on the ends and the later replacements do not.

Early '842 heads had plugs on each end. About mid-production 1969 went to one plug in one end only.

All '842 heads were closed chamber although I've seen
several sets with opened-up combustion chambers. I've
always been told these was done later on by owners to improve performance.
