Felpro head gasket 521SD with nitrous

Dang, I was going to throw cometics in it when the motor was out of the car.. But I had 1 week to get it in for the meltdown drags.. Only reason I'm asking is because in these early a bodies with tti headers you have to lift the motors out to change the head gaskets. I love the car but it's the worst car to work on. I'm going to spray it with 150 anyway
