BearsFan315 Posted November 7, 2014 Share Posted November 7, 2014 Can someone provide me with some Measurements ??Looking for some Dimensions on a 1929-1931 194 Engine with stock Components... I know that the Valve Head Dia varies, but the length is the same, Same Rocker Arms are used Casting No: 835549, and the Push Rods are interchangeable as well. So these Dimensions SHOULD be Pretty Darn Close on all 1929-1931 Engines !! Previous Owner seems to had a Head job done, want to know if what i have matches stock !! I need to know what the distance is from the top machined surface of the head (where the spring sits) to the TOP of the Valve Stem. WHEN THE VALVE IS CLOSED !! I want to see what the STOCK is vs what I have.Then the Length of the SPRING from Same machined Surface up to the top of the Spring, NOT INCLUDING THE CAP.Also a Stock Push Rod Length would be nice, so I can verify IF those were modded or not. Distance from Lifter end to Cup end (including cap on 1929-1930 engines)GREATLY APPRECIATE IT... Link to comment Share on other sites More sharing options...

X-Frame Posted November 10, 2014 Share Posted November 10, 2014 Does any of the GM Heritage Vehicle Information kits have that information?https://www.gmheritagecenter.com/docs/gm-heritage-archive/vehicle-information-kits/Chevrolet/1929-Chevrolet.pdfhttps://www.gmheritagecenter.com/docs/gm-heritage-archive/vehicle-information-kits/Chevrolet/1930-Chevrolet.pdfhttps://www.gmheritagecenter.com/docs/gm-heritage-archive/vehicle-information-kits/Chevrolet/1931-Chevrolet.pdfOr some of the books for those years at the Old Car Manuals - Chevrolet project?http://chevy.oldcarmanualproject.com/Scroll to find the year you want and what is available for them.Eric Link to comment Share on other sites More sharing options...
nearchoclatetown Posted November 10, 2014 Share Posted November 10, 2014 The dimensions you are looking for are determined by how deep the shop cut the seats. It could vary considerably from valve to valve. . Link to comment Share on other sites More sharing options...

BearsFan315 Posted November 11, 2014 Author Share Posted November 11, 2014 If you notice in the pictures, It looks like someone along the way did a Valve Job on my 1929 head. I am trying to determine IF what they did will work effectively and efficiently on my 1929 or do I need to get a new 1929 head and get all stock components.Stock Intake & Exhaust Valve InfoMake: OwnMaterial: Extruded SteelHead Diameter Nominal: 1 11/32Stem Length: 4 23/32Stem Dia: 5/16Style of Stem Mod: KeyTappet Clearance: .006 Hot Int & .008 Hot ExhSpring Pressure: 45 lb Valve ClosedValve Lift: .277Are Stem Guides Removable: YesAre Oversize Valve Stems Made: NoOverhead Valve Lubrication: Yes Link to comment Share on other sites More sharing options...
