So, what exactly did you buy and what was sent? Were the boxes and part numbers different? I've never had any luck with those perforated types with headers. I didn't think they were even supposed to be used with headers.
I bought the ones on the left in the first post, and received the ones on the right.
I'm with you on the perforated ones. I consider them last resort only.
These are on a 4 cylinder turbo that loves to destroy gaskets
