TR6 TR6 Engine Question

[RomanH]

I was wondering if anyone knows the dimensions of the counter bore at the top of the cylinders for a later 6 ('74)?
Specifically I need to know the depth of the counter bore It is not listed in either of the manuals I have.

I seem to remember reading that it is .014. I'll have to try and remember where I read it.
