No, they didn't fit this one either. the bolt holes in the block aren't deep enough, and even if they were the last thread of the bolt would be at the first thred of the block, even with the washer in place.
i think with all things considered, the stock bolts will handle the job just fine. i have a 340 and 2 360 blocks sitting here i'm working on and those caps are taller than those of the 318 block.
