[QUOTE="kaminari, post: 4386309, member: 100"] Hi bro, I think I better reply here instead of PM. Valve clearance for RB26 during cold start IN 0.45mm EX 0.38mm with valve max lift IN 9.80mm, EX 9.87mm (for your cam 270). Since your cam 10.25mm lift, you may choose to opt it by using shim but there is disadvantage using outer shim which tend to tilt out from the lifter bucket at high rev.Each valve comes with different shim thickness and need perfect measurement up to 0.01mm for clearance adjustment. Would recommend you change to TOMEI valve lifter which comes with 1mm thick high so It`s not necessary to use thick shim and merit for high rev. Still you need inner shim to adjust the clearance.It`s more suitable for 10.25 above spec such as 10.42 / 11.12mm OEM cam spec: 240°in, 236°ex ,lift: 8.58mm in, 8.28mm ex [/QUOTE]
