Cylinder Heads/ Cam upgrade

[Alex Navarro]

Hey whats up guys.. I need some advice and some help figuring out what to do… Im currently building a chevy truck 5.3 L83 top end.. doing a stage 1 cam upgrade with dod/afm delete and ported and rebuilt heads.. just yesterday I got my heads back from machine shop and i went ahead and started installing them.. prior to getting heads back I used one of the old head bolts and cut 2 grooves on it to clean out threads and blew out everything inside using pressured air.. a month passed and i finally got heads back.. when installing heads, the lower bolt hole on cylinder 8 location somehow got a little moisture in it when i was torquing down head bolt.. so far I only did the first pass torque spec (59 ft lbs) and have not done the second or third pass torque spec.. after installing heads i noticed a little bit of coolant dropped under engine passenger side.. my thought now is to remove heads again and clean out threads again thoroughly.. but my question is.. what can i use to make sure i dont have a coolant leak since im thinking I might have caused a small crack when i tightened down the lower head bolts?? Any advice or help is appreciated.. again this is a 2015 chevy silverado 5.3 l83 engine.. thanks in advance

Use a welder to fill the crack.
