The 243 and 862/706 heads all use the same length of bolt on the same block. IE you get the studs based on your block type. Head type in this situation has no bearing.

In 2004 they switched to all the same length.

In total a set of studs for you will have 3 different sizes for your application.
Long, 4 medium, short
(2 mediums per cylinder head)
