Big Boys Heads

[flatrod]

Yes I have a set of unused Big Boys, and my brother, Alaska Jim has Tony Baron heads. I bought mine from Paul years ago, I do remember talking to him when I got them, but don't remember much else.
I can compare the two if you like, I do know the Baron's are around 92cc, I don't think the Big Boys are that big chamber wise.

Thinking about it I think I do have some paper work somewhere, I'll look for it and report back.
