Newer hks 272/278
I would also recommend doing valve springs/retainers, larger lifters, and headstuds along with the cam install all at once so there's no doubts. May take a little longer to save up and do, but it'll be one less headache if you ever decide to do some spirited driving

Had them along with the new BB stock frame HKS turbo. Made over 460 to the ground. Came from having Kelford 272's. I'd say on a EVO IX they were milder then the Kelfords.
