The new cylinder block has an upper surface (top deck) thickness of 3/8 (.375) inch which is identical to an original cylinder block.
Port wall thickness below the top deck is a little thicker than stock at 3/16 (.1875) inch.
Although the intake valve size is stock, the intake ports are larger and more streamlined than stock.
I see that you are from Sweden. We have enough orders to send a container directly to our agent in Holland which will result in not having to pay US Customs.
