Hi Glenn.Just as a note, if you need to purchase a set of valve guides or valves, you may wish to convert your engine over to the newer solid guides.This is an easy conversion and is not any more expensive than buying split guides and "A" style mushroom end valves.This also makes it easier for a modern engine shop to do any seat grinding or seat insert work.The solid guides make for a more precision job.Let me know if you need more information.
Happy Model A'ing

: I am currently rebuilding a 1929 model A engine.I have a reciprocating valve grinder that I will use to grind the valves as described in Jim Schild's repair manual.
: Jim describes that the valve should have been numbered by the orignial valve grinder.
: If I am installing new guides do they need to be fitted to the valves?Is there any work required for the valve guides?Or is Jim saying that since each guide alignemnt is slightly different, once the seat is cut, the guide and valve should be numbered to the bore?
: I searched for info on this site but no one has asked this quesiton before.
: Thanks for your help, all advice is welcome.
