So lately i have worked on some engines with somewhat old AMC heads... so of
course, i have seen other scary stuff... after some e-mail exchange with Bob
Donald about those problems... i have uploaded my page to show you how bad
AMC valve are... or can be, because it's not always the case, that is the
real main problem!
