Started this yesterday and I'am just about finished , still want to address the valve guide in the intake port a little . One think I want to say about my porting is you'll see that the exhaust is polished , not like a mirror but enough to work fine . And when I do these ports I look at the exhaust is going out and to work the bowl in that direction. As with the intake the air is coming in so it should flow that way . Also with the intake it was pretty smooth from the sanding rolls used for shaping, but is finished up with a stone to roughen and to give it a swirl pattern . You do not want to polish the intake port , the fuel and air will not mix well that way .so that said here's some pics . Oh and one more thing the head has been sanded on my marble slab , took me two hours . It has had 53 thousand taken off . So with the piston 9 thou ITH and a 10 thou head gasket and the Honda flat top piston . This will give me a compression ratio of about 13.6 to 1 . Yes race gas for sure .
