roller rockers

[amcfool1]

hi i'm in the beginning stages of a 258 rebuild. thinking of going with the Harlan Sharp non adjustable rockers p/n S40196. these are supposedly for the 4.0. Will these work on a 258? I think they will, since the Yella Terra ones p/n Yt6627 are advertised as working on the 3.8/4.2/4.0. They are more expensive than HS though. Any ideas/opinions out there? thanks gz

They should work. Its the lifters that i have seen differant between 4.0 and 4.2. The pushrods stayed the same between those 2.
