Hey guys,

I'm wondering if anyone can shine some light on the header gasket on the CMB LS21.
I had gotten a standart cmb style exhaust gasket from a local hobby shop but it is way too tight and rips when you put the header on.
There's 2 grooves inside the header for orings it looks like. I have found orings that fit well.

Can someone tell me what they have as header gasket for the cmb LS 21?
And if someone has a diagram for that engine it would be awesome

Thanks
Mike

Try different size exhaust tubing or just o-rings to fill the gap might work
