No reason it shouldnt be reliable. Keep detonation away and you wont have to worry about headgasket problems. Nothing wrong with the oem paper gaskets. They get weak over a long long time but brand new there should be no issues.
Ive used the oem paper gaskets on a lot of rwd SR 350-400whp turbo builds and never had issues and thats a lot more stress on them than a little high compression motor will put on it.
