did i get wrong gasket,???

[EXDUNER127]

I just got my new 426ex motor back, and i noticed i ordered the wrong gasket thickness, i recvd the 89mm gasket kit when i needed the 88mm, can i still use this one if so will i be alright?

itll work fine,,, they use 89mm for 416 up to 440 you prolly got XR400 thinkness,,, gives you more compression
