86 Honda 70 Fourtrax

Hey guys new to the forum but am a lifelong Honda lover. Anyways have picked up an 86 Honda 70 Fourtrax and want to beef up the engine. Plan on going with a 88cc big bore kit from DrATV my question is I’ve found this Race Cam offered from the same website DrATV and am wondering if it is also a "bolt on" or "drop in" part? Will it work with the 88cc big bore kit and the original head? Any and all help will be greatly appreciated. Thanks!

Below is the 88cc Big Bore kit I plan on using along with the Race Cam that is in question.
