So I have the Badmab for my LE5. My dealer has the LSJ/extruded-honed gasket and the LE5 gasket. Which one should I get? Thank you

 

The one that matches your port...so the LE5

 

Damn it. I just had them order the LSJ one.

 

LSJ won't work at all? I figured it's the same, just the primaries on the header are bigger.

 

The lsj will work fine

 

Is one better than the other? I ordered then both from GM just in case.

 

Naaa same basic principle really...go with the lsj one though

 

In reality it doesnt matter but I would prefer the LE5 one. That way you have more gasket

 

LSJ gaskets are awesome MLS gaskets, and will seal up just about anything as long as the flanges are straight. Having "less gasket" isn't really a factor, as it uses raised seams basically to compress into the mating surfaces, it's not relying on large area but rather good pressure and a spring steel to maintain sealing even with temperature/pressure changes.

 

Interesting! I didn't know it was thicker!

 

So LSJ then?
