Will a 90mm h22 headgasket work on a 89mm bore? Purchased one advertised as 89mm but showed up it was 90mm. Guy says it should work but if i dont feel comfortable i can ship it back. told him i would ask the professional first haha. So here i am. Any info would be appreciated.

ps. setup is a 89mm darton sleeved block, cp pistons, pauter rods, p&p'd head.

 

I'm gonna say NO a 90mm is for a 90mm not a 89 return it and get a 89mm

 

yes ship it back ,,,and get 90mm

 

If you're running a turbo, you should get the correct bore size gasket. If you're N/A, the size difference isn't that bad, the gasket should hold up.
