| K.I.S.S. Standard valve Exhaust port pics |
| The purpose of this addition to the Dove exhaust porting tips is to show exactly where you need to remove metal from the port in its simplest and most basic form. You do not need to polish nor even touch the areas that are still the as cast finish. As noted elsewhere in the guide the thermactor roof manifold rail and the head bolt bump actually help flow so leave them as cast. Lesson here is do not over work the port... |
| Bowl diameter above seat 1.46" Note how short turn radius is rolled all the way over to the top of the 45 degree seat angle |
| Flatten head bolt radius |
| Note small size of exit and trapizoidal shape which is wider at the floor than roof |
| Raise guide boss until even with the thermactor boss using a p/c guide cutter |
