About the epoxy mod around the guide; it´s there to keep the port not stalling at higher lifts, just as moderncylinder said. I think It depends entirely of the port shape if it works or not. I wasn´t planning to do it at the beginning, but the way the port ended up, I felt it must be done. I Didn´t do any flowbench testing with that so I can´t be absolutelu sure if it´s needed. In fact, I didn´t do any flowbench testing with the port shape at all, I only tested a few variations in seat work.

I got the intake done today. It was a lot of grinding too, I had to remove about 25cc from each port to get the size right. Here´s a pic I took earlier. Who recognizes the intake?

OU812, I´m looking forward to see your work.
