I recently purchased some kelford cams for my build, the original plan was to run the 272β° cams, which requires modification to the heads to clear the lifter bucket casing. After some chat with the tech guys there I've gone a size down, what I've gone with are 264β° with 10.7mm lift, which is still a substantial upgrade, and the heads wont need modification. They're good for 700whp on a 2L, which is well above my goal! https://www.instagram.com/p/DBfjfKXygaL/?igsh=N3czdm9lZnlma3h2
