hey guys, my car just had the head machined for the first time and instead of going with the 1.2mm i went with the 2.mm.
i was thinking lower compression, so i could run higher boost.
was this a good idea?

Decreasing compression by headgasket alters the combustion chamber. How much was taken off the head??

I went with the 2 mill also, but thats only cause the head was warped all to crap and we had to mill alot off.

Search before you post. This has been covered a million times.

Putting a different size HG on your car is not a matter of preference it is a matter of what is proper for your given application. I don't understand how hard it is to figure out the proper HG size.... Ask your engine builder how much he took of the block and head, and get a HG that compensates for this loss appropriately. Changing compression with a head gasket is not something you really want to do.

It's not like you get a whole lot of change by changing the head gasket lol..
