i depend's how many part's they are going too replace , when i do a job i replace the cams + 4 cam follower's , 2 timing chains + 2 cam chain adjusters shoe's + gasket's & i go in thru the top of the engine & use the stock pushrods , not go in thru the side & cut out the pushrods & fix those ezi install pushrods thats the lazy way
Fattywa, if you put the 204's in I'd be real keen to hear what you think of them..
