ARP does not make the correct size studs, (the 4 inner studs are 1/10th of an inch to short.. i.e. they are 5.4" instead of 5.5")
I talked with the "custom parts" department at ARP and they can make them, but I'll bet it'll cost a bomb. My machine guy says that machining 1/10 - 1/8 of an inch is no real big deal, so that sounds more logical and way more practical.
Trust me you DON'T machine the head, just the seats where the bolts will sit, so you don't affect the head in any way...
