I've got a pair of new aluminium heads to go on my 302, with each of the heads came a pack of five black-steel top-hat bushes, these fit into the head bolt holes. Each head had ten bolts, only five bushes are supplied with each head, the supplier says this is correct. From what I can gather online they are 1/2" to 7/16" adaptors, do I only need five per head, if so, which bolts use them?
