Here you go -SEE LINK. OEM flathead spec is 7/16-14 Hex Head Bolt, 1-3/8" Long, 18 required. For a pack of 25 at $15 or so with shipping you probably won't find a better deal. I don't believe there are any blind holes on the block for the head but double check before inserting. These bolts are listed are 1-1/2" long so if needed dust down an 1/8" if needed. Hex bolts are spec'd at 65-70 ft/lbs. Ideally a Grade 6 (69 ft/lbs) or Grade 7 (71 ft/lbs) bolt would be ideal but not easy to find. A Grade 8 bolt is spec'd at 78 ft/lbs. Note chart as hex nuts used on studs are 7/16-20 and spec'd different. Also not torque sequence. Torque is properly applied in three steps at different settings, not all at once. OEM manuals show no washers are used too but I know some guys do.
