anybody know offhand what the thread size is for head bolts on a b20b block? i need to clean up the threads on one of the holes just need to verify the size...
 
Heres the tap i got. In order to get down to the head bolt threads, i needed a long shaft tap or an extension, I got this off ebay from L & N enterprises. Awesome tap definitly worth paying for imho.
