So Seth adds:
Those should work with the threaded rod I mentioned.

If you would rather buy than make, you could also look at the ARP Stud kit  - 
the SummitRacing part number for the 1/4-20 black-oxide kit is ARP  200-7603. 
It comes with eight studs and regular nuts and washers. The  threads for the 
nuts are 1/4-28 fine thread, still 1/4-20 coarse into the  cylinder head. I 
haven't found a pre-drilled fine thread tall nut, but they  may be around.
 
 
Oh - I forgot to mention why you should buy and drill ten of the tall  nuts. 
The answer should be obvious, though, the two extra ones are temporarily  
stored in the toolbox you take to the races. <grin>
