When the new DART block is available I want to buy one ASAP. However, what about head gaskets? Any manufacturer make a 4.125" bore LT1-style head gasket?

 

I use the Fel-Pro 1074's.

 

The bore on that is 4.125 I would expect some missalignment, guessing gasket hanging into the bore will be a problem.

 

you get cometics.....

you going to buy a high dollar blcok and use a $20 head gasket?


do some more homework.....read some books

 

I think I misunderstood. You want a gasket for a 4.125 bore or you want a gasket that IS 4.125 bore?

 

I missunderstood nothing. You recommended a 4.125 bore gasket for a 4.125 bore block. Here in the real practical world that wont work you need the gasket bore to be larger than the cylinder so any missalignment does not endup with the gasket in the bore.

Cometics is a good answer to what would work.
