Has anyone seen or have the actual written by Hudson specs on the factory head minimum thickness?
I know I have read that 1.94 (.060 off factory 2" thick casting) is the minimum. But I haven't actually read
that in any Hudson literature. Does anyone have that info? The NOS 308 head I have is only 1.98".
