A GT5 slant head without a gasket on a Raw non-slant engine. I bought a MM head for my GT5 and decided to install the stock GT5 slant head on my Raw 80cc engine. I used the same plug from the GT5 and so far, I don't have any problems. I do have a pipe and an intake on the bike but the engine pulls harder now and revs higher. I'm sure I picked up an extra MPH or two just from the head swap. This is just my .02 so feel free to bash this thread if you wish. I'm just letting you know what works for me. It's too dark now but I will post a pic tomorrow. I think it looks cooler too...
