We had to have a custom piston made with a 28cc dish. I am going to try to make my 2 1/8" pro parts headers fit but if they don't I will have to make a set. The lift is so much because it's a 55mm core. The smallest cam lobe they could grind is .480" and that combined with the 1.7 rockers they came up with this grind. The 4/7 swap is going to be interesting. Everything I read about that guys say it really smooths them out.
