Who here uses a cosworth head gasket?
So I blew my head gasket recently and I've been Searching for a good replacement. I decided to go with the cosworth but I have some issues. I found a 87mm 1.5mm thick. My motor is bone stock 86mm sr20det bluebird. I found some people that used the 87mm on the 86mm and say its fine. What I wanna know is How many people out there currently using a cosworth hg or any other , what the motor bore and hg bore, hg thickness, what mods are done on the motor ie pistons, how long has it been installed, and how much psi is are you boosting on a daily basis. Ty for the info.
