Quick history: engine started out as rebuilt 6 bolt block with 7 bolt head (head stud holes bored out for larger studs). i sold the car, a week later the guy called me saying a coolant line blew apart, and the car overheated. Head gasket was toast (MLS) replaced gasket with composite one, same issues (pushing coolant, head gasket showed damage even new one) Engine also has a BSE kit on it (i did not build this engine, it was in a car i purchased and pulled for use in another one...)
Took head back off, turned out it was warped pretty good, and it was decked way past the limit so i said screw it and put on a 6 bolt head that i had in the garage that was on a working motor. put it in the car, and now it gives this abnoxious ticking noise.
I know it could be rod knock, lifter tick, or bent valve but it seems REALLY loud to be lifter tick, but its 100% consistent which doesnt seem to be rod knock (changes perfectly with revs, load has no effect, and pulling injectors noise stays 100%)
heres a video to show what i mean. any ideas before i start tearing apart everything?
