Hi guys
I want to put on the the camshaft rb25det nonNEO, but don `t know how to choose the duration 265 or 272.
if you set the duration 272 WTC need to be removed?

and a maximum lift is possible be installed without rework?
an example of what I found, the camshaft kelford 272 9.3. installed without rework the cylinder head.

Measure the lobe to head clearance on all the pockets and you figure out how much lift the new cams can have.

Best ask supplier if VTC needs to be removed. Most after market cams won't fit the VTC any more.
