Cylinder head codes

[rubachuk]

I bought a modified cylinder head a while ago which was supposedly off a 1.3SR. I've just checked the codes against the one which I took off and they don't match, just wondering what the hell it is off.

Codes on the modded head:

Between cylinders 1 & 2 - 76124 and under that GMB
2 & 3 - GM
3 & 4 - 90 15 63 42
After 4 - 13 (in a big circle)

On the SR head:

1 & 2 - 199 and under that 5
2 & 3 - GM
3 & 4 - 90 080 936

Anybody shed any light on these codes?

Cheers

there are 4 casting no's for 1300 heads, but it sounds like that is a 1300 head if its got 1.3 stamped on it.

Sorry guys, made a complete balls up of that. I should've written:

Codes on the SR head:

Between cylinders 1 & 2 - 76124 and under that GMB
2 & 3 - GM
3 & 4 - 90 15 63 42
After 4 - 13 (in a big circle)

On the modified head:

1 & 2 - 199 and under that 5
2 & 3 - GM
3 & 4 - 90 080 936
