any ideas why there was a hole here

[/ QUOTE ] Those are the equivalent to turkey poppers that stick out when the turkey reaches temperature . They are put on by rebuilders so when you bring them in they can tell if the heads were over heated,if you try to remove them the warranty is void.

Chuck!

What's the vintage of these poppers? I've never seen or
heard of them being used before. As a matter of fact, of
the billions-and-billions of BBC aluminum heads I've seen
on the bay, these are the first I've ever seen. What else
can you tell me about their use and how effective they
really were? What was the timeframe such a device would
have been used? Inquiring minds want to know.....
