    Head Gaskets
    « on: March 23, 2014 - 08:36:59 PM »
     :clueless:  Hi guys,  for a 440  that's .040 over, what do I look for in a good head gasket?  Do they come in a size for the bigger bore?  Thanks.

    some do , most do not come is specific bore sizes  , what heads are you using , what is the compression ratio , is quench a factor ?

    I'm 40 over on my 496 and Fel-Pro had the right size.

    Going with Felpro 1009 gaskets that have o-rings, ARP head bolts , copper exhaust gaskets on Doug's Headers, New polished aluminum valve covers I'm sealing with hi-temp clear. Current cr is 10.5/1.
     Hopefully my quench will be correct. Edelbrock tech said should be good swap. Thanks for the input!

    If you are using Alum heads I would use Cometic gaskets , so you have expansion capabilities without tearing the gasket fibers

    Neal, I already bought the 1009's so I guess I'll go with them. That's what Edelbrock recommends. Hope they're ok. Thanks!

    They will fail over time how long depends , alum expands at 2x the rate of iron so the gaskets are constantly pulled as they expand & contract .if it is in the cold climate over winter & started in cold weather it will fail faster
