quick question: can the valve springs be changed without pulling the engine?

 

There's no need to pull the engine or the heads to change valve springs nowadays..

Just get you a good spring compressor tool, and have at it..

Check out the More Performance tool at thunder or the the Da Vinci tool.. It does two at a time..

 

And the air fitting to go into the sparkplug hole. Hook it to an air source and the valves can't open while your changing springs.
