ARP 135-3601 Cylinder Head Bolt Set
Is this correct for the Mercury Gen VI iron head engine, the OE Mercury ones have two lengths 4 inch and 2 inch, the ARP kit looks to have 3 lengths, looking to replace the OE ones,

That's the part number via search on Summit's site... for use with OEM heads using a standard hex head. ARP's site says the same. The mid-sized bolts (four in total, a pair for each cylinder head) go in the two lower corners.

ARP isn’t always sure about which set is correct, so I would recommend measuring what you need and comparing it with what comes in the kit. I had a set specific for Dart Pro heads on a Dart markIV and four of the bolts were too long. After speaking with ARP tech they assured me that the bolts were right and offered no resolution. I wound up getting the correct 4 bolts from my local speed shop.Good luck
