Looks like I popped a headgasket . Car is a 93 GT auto, p heads, trackheat intake, 100 shot of n20. The rest of the mods are in the sig. Need some part #s on good head gaskets for an n20 application. The car is mostly a weekend car with occasional track time about once a month.
I am replacing mine now. I was using the Felpro 1011-1 which in 500 miles, seperated a fire ring, necessitating the replacement. After using them, I started reading several threads about people have the same issue with that head gasket.
The Felprp 9333pt1 seems to get good reviews with several people running high boost levels and no issues. Thats the one I am installing now. As a bonus its a lot less expensive than that 1011-1.
Please update your thread when you get it torn apart. Im curious if you had the same issue I did or something else. Like I said in my 1st post. Seems to be a recurring issue with those 1011-1 and 1011-2 gaskets.
