Agree with Denny on your plug application.
Now as to those seals-My SBC sat for more than twice that period and did likewise smoke a lot. Advice from Tech1 was followed and seals are good as can be expected. Marvel oil to the mix and run the B-jeejus out of it. Kept a keen eye on the mirror. After about 300 miles I noticed a marked improvement and was pleased with outcome. That was awhile back and today the seals are ok. Used this procedure for 2 oil changes.
Good luck.
