Yes mine always leaked. I ran a thin bead along the lifter valley and down the back of the block. I mean thin. Then I did the same on the head side of the gasket. IT was more of a smear then a bead, but it worked. I'd never use them again.

You can use them but if the surface isn't to the finish they require ... they will leak unless you use a sealant.

if you have your surfaces machined smooth enough you'll be fine. i re-used a set 9 times before i developed a leak. just bought new embosed shims to replace the old ones & we were good to go again.
