Please Note:

Slight modification / grinding back of the the oil pump may be required when fitting this stud kit due to very little clearance between the top of the nut and the bottom of the oil pump. We have also seen on some models the stud makes contact with the Windage / Baffle Tray, in this case you will need to grind back the contacted areas.

This Kit is for the bottom end

These are NOT the head studs
