Unlikely to be 23mm lift. You are physically limited by the retainer hitting the valve stem seal at about 15mm (on a 2JZGE). Also the cam lobes hit the bucket bores when you have 11+mm lift on the standard base circle, necessitating relief work. I can't imagine another 12 mm taken out of the head right there. I also can't envisage a cam bucket big enough to accomodate that lift fitting in the head there. Did you mean 13mm? This actually is possible. The standard springs coil bind at about 9.5mm lift which is why most guys don't upgrade springs (almost all the off the shelf cams seem to have 9.3mm or less lift). Also, seated pressure is something light (42 lbs from memory). Add some serious boost - let's say 25 lbs - and suddenly your seated pressure is only 17lbs. Combine that with big rpm (>6000) and you can be assured to have valve float. [Report message to a moderator]
