QSC Gasket
I have a set of cast cylinders "QSC" that I am going tom use on my 2.7. Can anyone tell me what gasket to use on this cylinder. The picture shows the story. The one on the left Alusil has an o ring seal and the one on the right has a flat top.
Any help would be appreciated.

No gasket for the QSC cylinder. Seals right up into the head.

no seal or sealer! clean dry and smooth as the heads should be also.

No sealer. Head to cylinder sealing surface should be clean and in perfect condition. Buy this I mean the head sealing surface area should be as flat as the top of your new cylinders. Have you had you heads rebuilt and or resurfaced/flycut? When heads are resurfaced it makes the sealing surface perfectly flat and when mated to your new cylinders and torqued down gives you a great seal.
