    Well, it has 20 valves..
    Maybe blacktop 20V.. three spoke exhaust cam pulley
    does it have hydraulic cam belt tensioner?

    That looks like the blacktop tensioner, so unless they've swapped the oil pump too it's most likely a blacktop. And the ribs above the exhaust ports say blacktop rather than silvertop too

    measure the exhaust ports. 29-30mm id = Silvertop, 32-33.5mm = Blacktop

    That one looks like a Blacktop

    The back of the cam lobes a skinny, that means cams are blacktop,
    and the VVT solenoid is the type that looks like it has a strap over it, that is the blacktop type,

    Head is 100% blacktop as the top surface where the inlet gasket would be is straight, only blacktop do that,

    and as stated before the cam wheel and tensioner are all blacktop only.

    My bet would be a blacktop 20V.
