These are a factory set of 4 bolt main cap bolts with the shoulder under the head. I bought these from a PY member some time ago . In appearance they look good but, with anything so old I'm wondering ( short of magging) if they would suit a 525-550 hp street/strip engine w/o issues. The block was lined honed years ago using the original caps and bolts .Those bolts were lost and these are a replacement. Thanks, Mike
