I can't feel any ridge at all w/ finger nail (in the carbon free areas of course).

Yeah, at the cross roads deciding what to do w/ head(s).
HG still suspect but just not sure why #3 and #5 fouling.
Plan to pull valves tomorrow.
I would like to get prices on decent heads for compare to machine shop costs; any advice for good cyl heads?
Could a head crack that has leaked for a few years still be invisible to naked eye?
