ok so i just got my car back with a 408 and trickflow 235 heads. well i drove it and it kept loosing coolant so i checked the lines seemed good. fill it back up drive it come back its low again. so i check under the hood again and it appears i have 3 threaded holes on the front of the heads that dont have bolts in them. and it looked like there was a trace of coolant on the front of the heads, so is this where my coolant is leaking out. Do i need to plug all the holes or are there only certain ones that have to have a bolt. im going to call the guy that installed the engine and have a talk but i need to know what bolts i need to put in there. it appears the bolts that hold the water pump to the heads say 9.8 on the head should i just throw some of those in all the holes.

any help would be great

 

anybody?

 

those holes dont go in the coolant jackets

 

true, those holes do not go to your coolant jackets, they are mounting holes for accessories. More then likely if you can't see it comming from some part of the engine, or out from under the engine, then its going out your tailpipe and the builder needs to install some new head gaskets, preferrably some that don't leak.
