After assembling the engine I realised that ARP bolts on the conrod foul on the oil pump drive shaft (714 has chain driven pump).
That's how deep the hole is in the bolt centre
Because I don't want to cut into oil pump driveshaft for obvious reasons, I'm thinking about lowering the ARP bolt's head for a few mm. I just not sure how this affects bolt strength.
Are there any other uprated bolts with lower head available?
