It is necessary to inspect the S2 profile in your VVTi cylinder head for casting clearance prior to running. With the higher lift and the OEM castings verying, some require clearancing of the bucket bores and outer cylinder head casting to allow for the cam to spin freely and allow for enough room to not scrap oil from lobes . Please maintain 0.02" (0.5mm) clearance from the cylinder head casting.
