What problem are you running into with the ones you have ordered? How are they not fitting?

After installing a big bore kit (170CC) I also tried to replaced the stock head with a big valve head. It appears the KYMCO 150 uses a taller head than most heads on a GY6 engine. That places the camshaft further out from the crank. To use the aftermarket head I would have to remove a number of links from the camshaft chain.
I also found that the base circle on the stock KYMCO cam is larger than aftermarket performance cams. With the aftermarket performance cam in place, there was not enough adjustment on the stock rocker arms to even come close to setting valve lash.
So at this point I have a large valve head and cam that won't do me any good.

Your looking for a stock head?
If so, try a Kymco dealer.

Saw a few sites showing an OEM available but on backorder.
