Drive it carefully.. If you have anywhere after let's say 30K miles.. And you drive your car spiritedly.. The factory headbolts are stretching .. The car will drive fine for a little bit, then you squeeze it and it'll overheat again.. Good chance you HG isn't blown yet.. Get yourself a set of ARP headbolts and tighten it down.. The set is about 100 bucks.. And a very good insurance policy to keep the head locked down..

 

seems like a whole lotta work to replace head gaskets and bolts...if you paid to get it fixed how much was it? if you did it yourself how long did it take?

 

double post..

 

Guys...just because the overflow tanks fills up doestnt mean its a head gasket.
If the overflow fills under boost then yes.... when you shut it off and it overs flows, thats because its hot and is steaming and building uo pressure which over 13psi the radiator cap opens to release pressure.

Did you recently change coolant? Or had to drain it?
You may have caught an air bubble in the system.
Also some people dont check the fluid untill it's really low.
It is possible to lift the head with the stock head bolts at 23psi...


When you change the fluid, you can prevent air from getting trapped by parking on a hill and having the radiator filler neck at the highest point.
Or fill and start till the thermostat opens and releases the air, just top it off before you tighten the radiator cap.


Head gaskets can go and no steam through the tail pipe.
A compresson test and a leak down test would be the next step.
