I was really talking about the common 12G940 used here (Morris 1100S, Cooper S, 1275 Midget) and the smog 12G1316 (1275LS etc).
These will all stand having a lot off unless corroded bad inside.
I am aware the later heads are less thick, but there are hardly any over here really.
Hi Doc

,,
I had a couple heads out the other day picking out one for a bit of work (remember the one full of spiders

).
I started putting them away and I remember this thread and thought I'd take some photos for you.
This picture shows an MG metro head..
this pic shows a late model injection head
this one shows an old school 12g940
and this one shows an MG metro turbo head.
I took photos of these ones cos I remembered that we weren't sure about deck thickness between early and late makes... I couldn't get a good photo with the verniers but you can get an idea from the photos. There wasn't much between them,, bout 0.010-0.020" and none of them had much taken off by the looks of it.
Just thought you might be interested
I don't rearly know how old any of these heads are though,, thats the only thing,, I'm guessing the Injection head can't be toooo old though,,,
