Re: Installing New Headers
Yes you can. No need to pull engine. Like what was said above, the passenger can usually go in from the top down. The drivers side usually has to go from the bottom up. You will need to get the car as high as possible and be safe. Remove spark plugs and anything else you can see what might stop you. You may have to pull the dip stick out of the block too. If it's a stick, you will have to remove Z-bar and linkage. Worse case is you may have to unbolt motor mounts and lift engine slightly to get the drivers side in.
