After reading this post, I believed that is what was happening with my 427 SO. At one point I went through 6 quarts of
oil in 100 miles. I removed my Blue Thunder intake and noted wet
oil between the heads and intake gasket. I have the Edelbrock heads and used their intake gasket.
Per this thread I purchased the Fel Pro 1247-S3 from Napa. I couldn't find the Victor Reinz ones anywhere. I also used the Motorcraft TA-31 from my local Ford Dealer.
The picture is of the gasket retaining tool I made. Just a 3" wide piece of steel from my local ACE hardware store. They even cut it to length.
Thanks for this post. My car runs great now and no more burning
oil!
I did a few 390's back in the day, albeit with cast iron Ford heads. But never had this oil burning issue.
