How can tell if my top end is some cheap amazon/ebay kit

[borrelli4667]

I recently bought a 1998 blaster with a "fresh top end". It has a chinese carb and im assuming what is a chinese/ebay/amazon head that is silver, in my case ive always seen the oem blaster heads have a black coat on them mine is just silver and i have not been able to find this head anywhere online. Im assuming it was a quick fix and sell job but i dont know much and need some help diagnosing if the top end kit is just some cheap kit and if i should invest in better.

Hi, The silver head could be a Vito´s high compression head, check it in his web.

Watching your cylinder with no rubbers in the wings... I thing could be aftermarket, It´s easy to see in one side, let me go home at night and make 2 or 3 photos of the OEM sides.
