[Mgs] rocker threads causing problems

[Vance Navarrette]

	Gordie:

	Technically speaking, MG fasteners are not SAE, but rather are
Imperial threads.

	There are subtle differences between the two standards, but
since SAE was derived from Imperial, they will happily coexist in 99% of
the cases out there.

	There are a few cases where British and US/SAE parts will not
coexist, such a BSPT (British Straight Pipe Thread) for which there is
no US equivalent (that I am aware). However, BPT and NPT are fully
compatible.

	Just wanted to clarify that point, lest people think that MG
used SAE (Society of Automotive Engineers) standards - they did not.

	'Course, all of this ignores the fact that most cars now, even
US made cars, are metric. But we won't go there... It's a French system.
'nuff said. <evil grin>

Back to the original question, since some of the rocker studs are also
head 
studs, have you experienced the same on the other head studs, or are the

head studs okay?

As to the thread, it is standard SAE.
