cant say enough about them, they have some awesome products and their builds are excellent, we just got the headgasket for the build im doing for this de/ve hybrid all motor build, best looking headgasket ever, even others have said this such as miko, this gasket can be used with a 92mm bore, we are going with a 90mm bore 12:1 build 2.2L This gasket should hold up longer than probably any other part on the motor, haha. but seriously their products are top notch.
