Thought about it, but the whole point of angular torque setting and "stretch" bolts is to achieve much higher clamping forces between the rod and cap than can is possible with static torque bolts/method.
This makes for a more stable bearing journal and afaik all "modern" engines use bolts of this type and angular torque setting.

Not common with any other engine. Unique combination of lengths, diameter, design of head etc.
I have tried modifying rods to use 3/8" BBChevy bolts from ARP but the interference fits they use are mental. They actually stretch the big end out of shape, unless I fitted them all wrong.
I am not convinced that the cap location is correct either.
Earlier Porsche bolts may be an option but I have no experience of them.
