I have a 99 ls in my hatch. I am just built the head with a semi port and polish, 3 angle valve job, Crower 404, Crower valves, springs and retainers, Ferrea valve guides,seals, keepers. Bottom end is stock. I was wondering if it would be a big difference with a 3" short ram intake. Right now i have a 2.5" cai/sri. Will the 2.5" be bad or like would i lose power.
