i havent adjust the valves i just change the tranny cuz thats what i thought it was going (second and thirth were not going anywhere just reving really high) but no doesnt have anything to do with the cv joints its when i start it sounds like something is hitting clack, clack, clack something like that like i was saying someone said it was the valves hitting or something like that so i guess i have to do a valve job or rebuild the head right?
