Ok this question popped up with some friends while having a couple of cold ones. Instead of tying to find a good head then going though all the porting and machine work why not just get a head 3d printed with all they stuff done to it we want and crave it to have . Now i don't have any experience at all with printing parts. and i did find some Youtube videos of 911 head and a Ls block being printed in 82 hours out of aluminum so i know it can be done. Anyone know much on the topic ???
