Who sells rockers and Lash adusters

I have been all over the net, can some of you folks let me know who you get these parts from? I don't want to use the old stuff on the new heads I got. 2001 Cobra. 12bucks for a tappet is Hwy Robbery:bs: . I would buy used rockers if they had really low miles.. T hanks for any help Scott
 
there is a company that makes aftermarket ones, but if you think $12 for one is alot, you'll think their price is murder. the factory stuff is your only option. you'll have to get them from a dealership most likely.
