When purchasing new head gaskets do you want the same bore on the gaskets as the actual cylinder bore?
No, the head gasket bore size refers to the diameter of the bore and should be larger than the cylinder bore. If the engine cylinder has been chamfered at the top of the block, to make it easier to start ring assembly, the the gasket bore size should be at least that diameter. As an example, on a chevy small block with a stock 4 inch bore, the next gasket size is typically 4.030". Engines that have been bored out up to 4.040" will use a gasket size of 4.060". If you use a gasket smaller than the bore size, the gasket will fail as it can create hot spots that will cause pre-ignition. If the gasket bore size is too large it will create a cavity area that prevent a clean burn in the combustion chamber thus creating dirty emissions.

At what cubic inch does an engine go from a small block to a big block?
The Cubes inches of an engine don't determine if it is a small or big block.. The Physic size, mainly the Deck Height and bore spacing(not volume) determine it.Examples-from ford/chevy, late 1954-1990s(pre modular, LS):Chevy:small block- 9.025" deck ht., 4.4bore spacing, 265-400cibig block-(w and mark motor) 9.8" ht., 4.84 spacing 348-454ciFord:small block-(Y Block)- 9.77 deck ht., 4.38 B. spacing, 239-312ci.low deck block- 8.2" ht., 4.38 B. spacing, 221-302ci.high deck block- 9.5" ht., 4.38 B. spacing, 351ci.Big block-MEL block- 10.48" deck ht., 4.90Bore spacing, 383-462ci.FE block- 10.17" deck ht., 4.90 bore spacing, 332-428ci.385 series block- 10.322 ht., 4.90 bore spacing, 460ci.The largest production big block was the Cadillac 500, 10.81" deck ht and a 5" bore spacing. The largest small block is the LS base Z06 427ci.( 9.24 deck ht., 4.4 bore spacing.)Other big differences are the main journals and the weight of the engine. The weight and limit engine bay space is the main factors for the sudden jump in the size of small blocks. A 427 z06 engine aprox. 400lbs. vs. a 600lbs 427 bigblock.
