There is nothing wrong with the ACL gaskets, just make sure you don't use any hylomar on them as much as you may be tempted to - as they already have embedded sealant for the waterways in them. Just make sure you clean up the deck surface really thoroughly of the old gasket and dirt with a paintscraper or similiar and then give good elbow grease wipe with clean rag and thinners or acetone. although they don't recommend this, I retorque all my headgaskets at 500kms and then 3-5000kms. seems to be the trick. Apparently there was a japanese gasket brand called KP that was really the bomb before ACL came good but I don't think they are around any more.
