| Ported these heads have great street stormer potential |
| For those of you who haven't seen these castings. The intake port has been raised and has a better approach to the valve pocket. It is on the smallish side as cast. Very high velocity though Intake valve size is 2.0" until '93 when it was increased to 2.08" |
| The exhaust port has been completely revised. The floor is filled and raised as is the port roof. The exhaust flange centers are the same as the earlier castings as are the exhaust bolt centers. |
| They also use center bolt valve covers |
