The cylinder head and main cap bolts are easy enough to identify. Now going through the rest of 'em to find what's missing. Main concern is the correct camshaft bolt and the oil pump bolts. Some will be re-used others will be replaced. These come from a "complete" 340 core motor I purchased in Sacramento some years ago.

Photo #1: cam thrust plate (four-one with hole), two unknown; #2 one dist. hold-down, two possibly fuel pump (integral washers), five unknown (loose washers); #3 ten rocker shaft, ten exhaust manifold, four large unknown, three small unknown, three misc unknown (short, medium, long); #4 twelve intake manifold (one shorter than the others); #5 twelve oil pan, four unknown (smaller w/washers); #6 nine-probably valve covers (two shorter than the others); two unknown long bolts (with washers); #7 various water pump/timing cover-two very long, six long, 4 short, 4 very short.

Camshaft bolt may be the middle one of the three in photo #3. I don't see any obvious oil pump bolts. Correct on the fuel pump, oil pan, intake, and valve cover bolts. Exhaust will depend on the year, as some use those sleeve bolts, and there should be some nuts with the cone washers for the end studs. As a general rule, the ones you find with rust and/or paint will be exterior fasteners, whereas internal ones are usually oily and not rusty or painted.
 
i don't see the cam/fuel pump eccentric bolt/washer in there.

i'll compare and contrast what i've got bagged and tagged to what you've got here later when i've got the stuff sitting in front of me.
 

The early cam bolts (like our 273's) use a 1" long Highland grade 8 bolt for the cam washer, and no lock or flat washer is used with it. The bolt head has the castleated look to it with the H in the middle. Stock oil pump bolts are 1 1/2" long and are grade 8 also.
