my Low dollar 318 hop-up project

I think I forgot to mention in the videos that the exhaust port that has the extra port that goes to the intake manifold gets a little different attention. I just try to port the flow towards the exhaust port instead of making it head towards the intake manifold.

Also, to those that are wondering why on the intake side of the port entrance, why I suggested just a straight file between the two intake ports to smooth the casting at the entrance and recommended not thinning down that wall is simple. I like a good surface to be sure of no gasket leaks. If you want to thin that wall down, you might gain a small amount, but I don't like to do that.

P.S. - I got just 4 more intake valves to do and the port work is done :D
