Not sure this will be of any help but the 49-51 Merc Manual says:
1949 and 1950 valve clearance (cold) .010 " to .012 intake and .014 to .016" exhaust.
1951 Merc valve clearance is shown as .013 " to .015" intake and .017" to .019" exhaust.

Another reference book shows 1953 Ford 239 V-8 is .014 " (cold) for intake and .018 " (cold) for exhaust.
