** NEW ** Trick Flow LA cylinder heads introduced at SEMA
Can there be problems with head gaskets blowing when they are considerably thicker? It makes sense to me that since there's an increased space that's not solid metal this could be an issue. I've read all the pictured books, still learning. What I don't want to do is buy a set of heads just to find out I can't get to a CR that will allow me to run pump gas etc. or have a street engine. These are new heads but what I'm hearing here is closed chamber is closed chamber, guess I'm too concerned with what the manufacturer is saying.

Not if it is designed for it. IF the gasket company makes a .080 gasket, they designed it to work.
The manufactures have different specs and out looks as compared to high performance companies, race houses and teams. The manufacturer has to meet longevity, emissions and such concerns the general John Q. Public doesn’t want to contes or deal with ever.
Once you get into modifications for more power, beyond the factory components, some issues can crop up that were never introduced to the working parameters of the stock engines.
To use a (very) thick gasket, I suggest going to Cometic for your gaskets and pay the price. I am currently using .100 thick head gaskets on the wife’s car. (The very last person you want to hear whine, complain, *****, and point a finger at yourself with!)
Further back in time, I had a very high compression 360. Then came disater with the everyday car and a NEEDED my hot rod retuned for daily useage.
I ordered up MP’s cylinder head gasket steel shim and used a pair of gaskets in each side to drop the ratio like a rock for 87 octane. It was used in a 80 mile round trip commute for about a year without issue.
