What casting number heads on a 70 350?

[Davetopay]

Any one know? I was just curious what SHOULD be on my motor. I do get the feeling that it has been gone through at some point though as the head bolts are now studs. Should this be a 4 bolt main or 2? I haven't been able to find the block casting number on the pad behind the alternator. Could it have been milled off?

I am just trying to prove to myself what is going on under the hood of this truck. I keep seeing engine bays with the alternator on the driver side, but mine is on the passenger side. The block has been studded in place of head bolts....numerous other little things that make me wonder if the engine may be a swap job. It does have power steering. I'll have to get down to some cleaning and break out some mirrors to see if I can find the bell housing pad numbers on the block because there is nothing to read on the passenger side at the machined pad by the head.
