Be sure to clean the head bolt holes out very well so the new header bolts turn in as easy as possible. I used Stage 8 header bolts:

However, I did not feel it was necessary to install the locking tabs that came with the bolts. Summit has listing for a set of 32 bolts specifically for ZR-1:

The small 12 point 8 mm head provided a little extra clearance in the harder to get at holes.
