Bronze valve guide liner install J heads question for machine shop guys...

Stop looking. Lisle hasn't made that for decades. No replacement parts are available. Unless you are getting into the cylinder head reconditioning business, do yourself a favor and have a machine shop do it. Don't half *** it by doing it yourself.
I have to say I agree...so many stock heads out there that need rebuilding though but they are getting old also. Im fortunate that I have a decent set of x heads and two sets of j's my last set of Js need redone Ill spring for that ( Im thinking 700 bucks in todays money) then have 3 sets that work. Thing that is unfortunate is who would pay 750 for redone J's ? mayve in 5 years or so...:)
