how hard are heads to install ?? just need to disconnect headers and manifold ??

and need new gaskets ??

 

Last, think plenum repair. Then yeah add in removing headers/manifolds,and valve covers.

 

in a nut shell...yes. but make sure you have someone that knows what they are doing. the push rods can be tricky...put it in wrong and it will miss the lifter and then you get to remove the whole intake to retrieve it. also, valve adjustment is another biggie.

 

where can i get some good heads

 

just gotta keep your eyes open. Engine Quest is the best...IMO...if you are gonna buy new.
