Block and head groove?

Krooser said
The 1008 FelPro is the most popular for high performance small block.

My SBM was built for 13-1 and has neen oringed. That was back in the mid 90's when gasket tech wasnt as good as today. After it was redone in 2007 it got 1008's.

So the 1008 work with the o rings?! That's great to know thanks for sharing!
