That is a drain back from valley to t/chain area I would cut more of the lip off the bottom of the hole

mostly the cause on the OLDS for milk shake is a poorly seeled intake and to much pressure in coolling system  Good luck with the build  :thumbup:

I do have a set of KA marine heads and a 30 over short block with forged pistons also a marine block  ;D
