[big job]

Before everybody goes bonkers on this subject this is how its done. go to y tube punch
in "fiat nutzs ford flathead valve adjustment" John runs a top end machine shop in CA.
He came up with this researching this subject the way the factory did it but the factory
of course had massive tooling, meaning 16 valves at a time in seconds . well we have
not those deep pockets but with this simple jig & one at a time he machines and sells
these jigs. I made this jig before watching his vidio My jig a good valve guide clamped up to bench grinder with fine wheel use the side of the wheel nip the stem watching the dial indicator. To start yes it takes time but time spent is I own & it is in the draw .
couple things with solid's 1 loose lash then face the valve or nip the seat to set it deeper then grind the stem fastest way out buy chevy valves that are longer then no need to fool with seat and valve grinding. This is not for split guide engines .
