Depends on your heads. They are 8cc dish normally 9.1 on ported heads.

Nobody is building low comp motors since 2004. The higher comp is when everyone started running faster and that was why. They have a lot better low end and throttle response at lower boost levels. This comp ratio is the sweet spot for high power out of the 5.4
