11 studs

Sooo, is there anywhere I can get proper dimensions from?
I could take measurements off the old block, but they may already be drilled at tolerance limits, so I could end up too far off location.
Or is it just best to wait for an 11 stud head to turn up and use that as a pattern?

if you make a slight mistake on this it could be a lot more expensive .
a machine shop will have the correct size drilling machine to do the job with minimal effort . home bench drills flex under strain .

hi do yourself a favour and get a local machine shop to do it for you

Thanks for the advice, but it'll be done on the Bridgeport in the machine shop at work so it'll be fine really. I was wondering about using the head gasket, but I wasn't sure about how accurate it needs to be really.

yip u got it just didnt want you attempting it at home if you get me
had visions of a big mess
Lol, no probs, like I said, thanks for the advice. If I were actually going to drill/tap it it robably would be a mess. But I think I will get the engineers at work to do it!
Only problem is that the engine is built up, so I gotta be MAJOR careful with swarf etc. I am thinkin of wrappin the bugger up in clingfilm before doin it and pluggin all of the holes etc. I really don't want to do a full strip down to do it!

a head gasket is how most engine builders i have seen do it, and its what i am going to be using on mine.
on the new minibuilded dvd bill sollis says the hole closest to the water pump breaks through into the water jacket so that may not be such a good thing if any swarf gets into there.

most of the answers i got were its not needed
and what made sence to me was if a MG metro turbo engine is ok on 9 studs why fit 11 to mine

when i bought my new cylinder head it was a 11 stud head at the time i asked on here if it was worth me taping my block and using the 11 studs
most of the answers i got were its not needed

Maybe it's worth me asking Mr Cylinder Head supplier, see if he thinks it needs the extra two. It is going to run a high compression ratio (11:1), so I think the 11 studs will be necessary meself.
The water jacket thing is a concern MOWOG. I was looking at the block yesterday and was thinking that there wasn't much metal between where the front stud goes and the water pump cut-out. I will have a look at me other block and see how deep that one is drilled.
