The Blacktop piston is extremely different, to accommodate for your much larger chamber the dome is substantially higher with lessened flycuts. The exhaust flycuts remain existing but far more shallow and only the center ingestion flycuts stays but even that is just a tiny flat circular dish machined out.
Additionally, it has higher compression ratio, and reformulated combustion chambers to improve the fuel overall economy and emissions. All variants used belt-pushed SOHC 8-valve counter-move cylinder heads with just one downdraft carburetor.
– Port profile / transitions: No edges, adjustments in angles or nearly anything but a clean inner port end to the least degree of drag / turbulence.

A piece of hose to your ear, Keeping it at the exact same spot for each's 'hiss' for comparison - Appears equal, They're equivalent.
Generally the belts can’t be swapped in between engines however, if the complete tensioning system (16V / Silvertop: Oil pump, spring tensioner and tensioner article fitted to dam) is changed / equipped then a Silvertop belt can be used over a Blacktop.
