Default Optispark install question

After taking off my heads and getting them shaved down and new valves, I fired up my camaro. I figured it was an ignition problem. I got my optispark off today, was wondering if I should replace this gasket/o-ring.

That's the optispark seal. If it looks to be in good shape you can reinstall the opti. It's cheap though, so you might want to just go ahead and replace it.

Keep in mind you'll probably only be able to get it in a pack with the other timing cover seals.

There are no cracks in it, still feels rubbery. I doubt a local store will have it, so I will just go ahead and install my opti tomorrow. Thanks for the info.

You can get it separately.

I just replaced the Opti on my car after 115K miles and I replaced all the timing cover seals. It will probably **** you off if you have to change it soon after you get it back together because of a leak. So my recommendation would be change it while you've got it apart. I believe the part number is #12552428.
