unless you are going to run a close chamber head...which J heads are not....zero decking the block is a waste of money...you can get the same compression with the thinner head gasket...

Glad to see these in stock somewhere. They were hard to find for a while. I disagree about the decking though. Not a waste of time or money. It'll insure that a zero deck is what he gets and with the heads in use (to be used) a popular gasket from Fel-Pro is always available. The slugs can be deep in the hole. Deep enough that the thin head gasket will not make up for the distance. Moper has had a good run with the KB-107's being a bit deep. I myself have had a 50/50 with where they sit in the block.
