Cam Help

I just bought a block .040 over with pistons with supposedly cast iron Victor Jr.'s, all gear timing gear set (instead of the timing chain), he said E cam but i just found out its a Lunati cam hydraulic flat tappet, hydraulic flat tapped lifters, billet flywheel, like new valeo clutch and pressure plate, brand new studed 1.6 rockers, water pump, chrome oil pan not bad deal right? My question is did they make cast iron Victor Jr.'s and if they did how can u tell if they are? I found a J/R on each head in the oil galley section where the valve covers go over. Also what kind of head gasket could i go with? One more question the back of the cam has 3 different numbers it has Lunati then under it 00061 then somewhere else it has 07301 and another number which is very faint is 210670. Could someone please tell me what kind of cam this is? Maybe the specs or just what its made for?? I cant find it anywhere Any help would be appreciated.
