hello i asked this question but how did you all drive you car after a head gasket change. the problem is that i need to take the car for emission test in washingtons state to get new tabs for the car. But when i bought the car the i didnt register it becuase in order to do so i needed to pass emissions but it never did. so i rebuilt it and now want to go get permits but ive heard from people saying dont let it gain boost not even 2 or 3 psi of boost. ok so when should i shift when did you guys shift around what rpms please list rpms. People say i shouldnt push the car until 500 miles so no boost for 500 miles what should i do? its a 7mgte supra its got original toyota head gasket but arp head studs
