Question, I will be posting in both sections. I've been told the m20 mating surface is the same regardless b25 or b27. i want to run the elring kit over vr headgasket because of the reviews. One says that it will fit the b25 and not b27. If there is a weird thing that doesnt allow this please let me know. Car is boosted with a built head. I dont plan on keeping the motor too much longer so a stock head gasket and head bolts will go back in. I want a different motor setup so this is just going to get slapped back together for the winter and run hopefully in the spring. I would like to know of your opinions please! thank you.
