    Ford 302 aluminium head - bolt query

    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?

    I'm guessing as in pic 3....something to do with clearance on the casting for the hex bolt...?

    Probably wrong.....

    Quick Google shows the sold in sets of 20 to adapt stock bolts to aftermarket heads...yours will accept bigger studs without the bushes for when you put those twin turbos on it...
