head oil suppy ?.

so thanks alot guys who helped i know this isnt a regular rebuild and being a mag block its different to most but i will check into the angle at witch it was drilled as to i am curuies about that head oil passage.... i heard thats all i had to do to the block to adapt the two.
i do know when at the machine shop we stuck a wire up from the cam bearing and it went half way up the gally to the deck before we drilled through the deck. hmmm no worries i will fix the problem.
thanks again to who helped as my 550+ hp 408 is on the way.....i just want to go fast like sum of us. you live and learn...
