I understand the bowls are thin on the early 810 casings, (freeze pugs) even though I've never ground through one. If it is an early head, they have really small ports. Make them bigger. You have to work on the short turn, I don't care who said what. It's all in the shape. I can't really explain that and it's almost impossible to get "right" without numerous trips to the flow bench. Just watch grinding too much, here.......on the straight wall side. Good luck. 5904169-5664623-w2engine016.jpeg (128 downloads)

Thats exactly the kind of info im after right there.I always thought that a "glass" type finish was ideal ,but i guess not.So finish out with a 60 grit roll ,got it ... http://www.youtube.com/watch?v=ykcsXMV3vfg My Dart ,and im just getting started...
