Looking to replace my heads, or just keep my factory heads and replace the rocker arms, push rods..etc. but im not sure on what the specs for the factory heads are. Anyone have knowledge in this area, or advice for which heads i should just buy for the 5.9 THankx

 

just found this site with info, any of if correct?

I would just pull them off take them to a renowned machine shop and tell them to do a valve job and port and polish the heads, she will run like a raped ape
