Official group buy -350 MLS headgaskets

Has anyone use these gaskets yet? I was just getting ready to put mine on and just for fun put a dial caliper on the and the bore size is 3.815?
It was checked with two sets of calipers here and at the machine shop, is this right?
Thought they were .030 over bore...
Maybe I am missing something?

 

Bump to the top, anyone use these yet?

 

These are the Thialand gaskets right?

Any feedback on these from anyone that used them? Thanks in advance.

I just wanted to chime in here and let everyone know that my "gaskets to go" head gaskets will need to be replaced by the company that made them.... They are far too small in the bore opening, they made a mistake... I am calling them tmrw to get them making me some new gaskets and I advise everyone else to do the same or at least measure thiers... These gaskets are useless as is....

 

Had a similar problem from flat out gaskets. Bore right but big Buick gasket. Who runs a 3.900 bore on a big block? Anyways the have corrected them and are available from buyraceparts.com racetec. Account for the .050 thickness in gasket thou. Stainless steel combustion ring.

 

AND, they are suppose to handle 20 psi of boost to bat plus they come in 2 different bore sizes, 3.840" and 3.905".

Mine worked fine, but I wasn't working them too hard. I have no idea what happened to them though.
