Nope. Unless they've changed the rules since I left, you are not only limited to a 0.5 compression ratio increase, but you are also limited to 0.025 machined off the head to achieve that. If you exceed that the head gasket thickness won't matter. You also have to run stock type pistons. There are many things engine, suspension, cage et al that you can do in EP but cannot in ITS. If you're anywhere near competitive in EP you'll be illegal in ITS. Build one of the other, IMHO.
