Blown BBC Head Gasket, ADVISE?
Heres the Deal?
427 T/Deck GM Block.
NO O-Ring Grooves,this Motor was in a Nost.Funny Car,and Ran Pretty GOOD!But,with Only 8-Passes on the Combo its a Hard Call?
Currently I have a set of Merlin 345 Iron Heads(VERY HEAVY)but a Good Head for a Blower Combo!
Heres My Delema?
This is going in my 95 S10 Back/Half Truck,standard Cab,so theres NO Room to Slide the Motor back!
I have a chance to pick up a Nice set of Edelbrock Chapman Heads (ALU)so that about a 150lb Swing.
The Motor had a set of Cometic Gaskets,that were sealing just FINE!
If I go with the Alu.Heads?
Will the Cometics be the Ticket?
OR?
O-Ring the Block and go COPPER?
Which is the Way I all my Old Motors were.But?That was before these Cometics were Invented?
Any Thoughts?
Thanks!

Blown Big Block head gasket
I did not mean to down grade the Cometic gaskets. In fact I ordered a set today. I was just trying to offer an alternative to having to o ring the block.
The Cometics do require a very precise, fine finish deck surface on the heads and block to work. They do work fine if that is done.
