Cometic is correct.

I have run them for years, no problems here. And they make a 93mm bore gasket which OE doesn't.

I know DSM guys had issues with them because the embossing was not deep enough, but on these it looks as good as stock. I can't find a single 3/S that is running them that has problems when I search.

I suppose we will see with big boost, I also have A1 studs and the head mill was damn near mirror like. I had no problems at 20psi.

Just pulled her apart to do new forged rods and then found out I had some corrosive coolant action going on that needed to be fixed.
