Just had the Comp Cams website up, looking at that very "gadget" when your post arrived. I'm leaning toward the Comp Cams rollers now that I'm out of the other two options.

Just as a curiosity question - Miller Rocker arms - any thought on them? I came across them for SB Fords while 'wandering' the internet, and for less then $200 - not going to use them, it's just a new name to me.

miller mid lift rockers have been around for a long time. guy ran a 429 hemi head engine and started back late 70s? playing with rocker arms .l looked at his stuff many time read threw is history back sometime ago at that time he did get in to some of the flaws of some of the other makers of roller rockers it was a good read pretty much confirmed what i seen going on over the years with all the different makes of rocker arms and fighting with them getting them to come in right for mild lift thats about that time i pick up my ferry head tool mild lift checker . for push rods i have many. ones i like the most are jesel as you can add to them to go down to 6 and screw more tubes to gether if you need a push rods past foot
