I have new toys and want to play with things, I also like it when people ask what kind of part is that or I have not seen that before. I like what CarPlay said" the chicks will dig me". Seriously I have access to a milling machine and tig welder and thought that putting the plug angled in the head would be a cool custom look along with some other mods I will be doing. I will be posting a build up mini drag bike out of my Cat slingshot very soon. The cool thing about these motors is there are a lot of them and they are cheep, not like custom building a motorcycle or car/truck, been there done that. Thanks for all the replies and pictures, I was curious about those after market heads and what the combustion looked like
