On mine I had to use more hood hinge shims in the back to bring it up proper to the cowl area on the fenders... after that I adjusted the hood hold down latches behind each lamp. If you pull the hood down to far it becomes lower than the fenders... if you still need more, like I did, then you have to start sanding away at the inside of the header where it is contacting the core support. When all that rubbish was done the header was almost touching the very center of the hood and on the outside there was a 1/4"+ gap. The only way to solve that problem is to reshape the backside of the header to get a consistent gap along the whole leading edge of the hood.
Lot's of fun.....
