identification ? mk1 or mk2 head

Postby nedski » Wed May 07, 2014 10:56 pm

Hi
A question for the great and good.
Ive just taken a cylinder head off a mk1 but it's slightly different in the water jacket area, combustion area is very slightly different and i think the inlet port shape under the valve.
Any Ideas. I have a couple of pics. Normal on the left and different on the right.

Again the head above is different to my other mk1's

thanks anyone. My guess is it's a mk2 head :confusion-confused:

I believe the 94-97 and 97 on are different, without checking, there's a skinny port head and a fat port head on mk.1's but Andy would be your man on this

They are both 1.8 mk1 heads, early & late. BP05 is cast into the back. Mk2 1.8 heads have BP4W and mk2.5 have BP6D.
Regards.
