Alright mate, got a newman in mine.....didn't bother changin the seals or bearings tho!! The 'special tool' is for adjustin the solid lifters, as u need to set the clearances between the lifter and the rocker which is a bastard of a job to be honest mate! Best way i found was to put the tool in a vice and clamp it up, before puttin your lifter in it and doin up the allen bolt on the tool to hold the lifter in place while u adjust it. Dunno if you're familiar with fittin solid lifters but u'll need a set of feeler gauges n all to set the clearances as they're tiny!! Hope this helps
