i've been trying to figure out what kind of heads are on my car. the stock spark plugs don't fit but the heads look stock. they have these codes on them: 3D27 and on the other it says 3D28. can anyone tell what they are?

pull out a plug and tell me the part number and brand, or get the casting number off the head (like E7TE or F3Z)
