i want to figure the compression change with a few factors of a motor.. and i have the formula, i just dont have some of the numbers to plug into the formula...

all the numbers i need are from the L03 305 TBI motor, what i need is the stock deck height, stock head gasket thickness, stock dome height on the pistons (negative number i think? -6cc or -8cc... not sure, thats why im asking hehe), and the bore of the pistons. is it 3.74" or 3.75"?

thanks a lot.
