Engine: Valve clearance - 1932 Studebaker Commander eight model 71

[skyrider]

I want to adjust the Valve clearance with my 1932 Studebaker Commander Model 71.

Who can tell me how much Valve clearance the intake valves
and how much Valve clearance the exhaust valves must have?

Nobody knows that???

Thank you

I tried a Google search, but this is all I could find so far.
I have a Motor's Manual from the 30's that should have the specs, but now I have to find that book.

I found my old Motor's Manual. It calls for .004" intake and .006" exhaust running and hot. I like to set them cold and not running, so I would add .002" to each of those clearances.

Setting them on a running engine can beat up the feeler gauges.

I understand this propper? 0,004" and 0,006" if the engine is hot?

Thank you very much!!

It's hard to keep a flathead engine 'hot' during valve adjusting. Here are specs from the shop manual:
Intake valves, .004" hot (,102mm) .004" cold (,102mm)
Exhaust valves, .006" hot (,152mm) .007" cold (,178mm)

I don't know what the exact specs are, but, as a general rule, a few thou too much causes no harm, a few thou too little burns valves

That right, and it cost me a valve job on my 1949 Chevy 1 1/2 ton truck back in the early 80's.
I figured going a couple thousandths closer would make the engine quieter, but within a few weeks I had a couple burned exhaust valves.
