im going to be taking my head off sometime this week because i believe i have a blown headgasket. now, my problem comes when selecting a new gasket. i have a b18b that has been bored to 2.0L, what type of gasket should i get?? should i get an OEM B20 gasket??? (i know it sounds stupid, im just guessing) or should i get a oem ls gasket and cut it out??? also should i get an aftermarket gasket or just stick to oem parts???? thanx
