um 
you sure about that? because I've been running this cam for 14 years in a 20R head and a 22R head and Ive never used any "beef kit" and no you dont have to 'hone' the valve guides. where did you hear that??
the ONLY thing I had to do with this cam is some clearancing of the pistons.
Quoted that directly off of LCE's site. It says "WARNING: LCE highly recommends using our Pro Camshaft Kit Part# 1020000 in order to allow proper spring retainer to guide clearance for any cam that has over .450" lift or in any application that requires a sustained RPM of 6,000 or higher" and that cam has .460 of lift. It also says on their site to hone valve guides to proper clearance.
