that swept area issues, is serious. issue. (as serious as piston 1 to hole 2 (large to small)
16v old pistons, in to any old 8v block
that top ring on that 16v piston, may hang up on the upper ridge of any well worn 8v block (25 years of wear? ) if well worn the piston size mismatch may go away but not this)

if the added an alien piston 16v to 8v is that, and the #1 ring is higher now... check that yet?
then it hits this point (ridge) then the ring shatters.
bam a wrecked block.
in school before pushing pistons , out the top (crank still in block)
we ridge ream it first.
