Gary_Ash Posted May 12, 2021 Share Posted May 12, 2021 (edited) The inlet valve is p/n 127279, the exhaust is p/n 127273. Graham Gagne has some in stock in Canada. See http://www.canadianstudebaker.com/Engine.htm under Valves. Milt Yoder may still have these: Posted May 13, 2019 I am going thru my engine parts and found I have the following, I believe they are NOS and NOSR, if any one is interested please email me. They came from a Studebaker dealership many years ago.

Gary_Ash Posted May 12, 2021 Share Posted May 12, 2021 (edited) Egge claims to have the valves and other parts. Not cheap, but available. https://egge.com/kit/st230m31/ Edited May 13, 2021 by Gary_Ash (see edit history) Link to comment Share on other sites More sharing options...

Mark Wetherbee Posted May 13, 2021 Share Posted May 13, 2021 (edited) Those are very close to the valves in my 31 Pierce 8 which are available through John Cislak in Springfield MA, but a tad shorter- I don’t know if he might be able to get them done up shorter for your car??? here is the factory specs for the PA valves: Intake Valve Material: Chrome Nickel Head Diameter: 1-21/32 Bevel Width: 3/32 Guide Clearance: 0.001-0.0025 Stem Diameter: 0.3725-0.3735 Overall Length: 5-41/64 Tappet Clearance (hot): 0.004 Exhaust Valve Material: Sil Chrome Head Diameter: 1-9/16 Bevel Width: 1/8 Guide Clearance: 0.0025-0.0035 Stem Diameter: 0.3715-0.3725 Overall Length: 5-41/64 Tappet Clearance (hot): 0.006 Edited May 13, 2021 by Mark Wetherbee (see edit history) Link to comment Share on other sites More sharing options...
