That's my plan for tomorrow. Disconnected the battery and started with no lights. Let it run for 30. Still no lights no tell tale exhaust ticking. Just curious but does anyone else have a whistling/whoosh sound with their headers? It is a pleasant sound but just curious if anyone else had this. The nice thing about CELs is that it is the computers way of saying "you haven't gotten it quite right yet so give it a bit of tuning. " Wish my 64 Falcon did this.....
