bigger bolts!

update image

The 9mm head bolts have a max torque spec of 36ft/lbs. To buy uprated ARP bolts would set me back $129 from a Fiat supplier. Isn’t it handy then that the two different lengths required are the same as small block ford. SBF’s however are a slightly larger bolt at 7/16”-14. The larger headbolts have a can be torqued to over 80ft/lbs and a set of ARP’s is only $49. Just have to drill out the head and tap the block
