I have a 67 Nova that takes 6 different wrenches/combinations of wrenches to R&R the 8 spark plugs.
There is no magic formula or "silver bullet".
Besides the usual spark plug socket with a ratchet, I've used a combination wrench on the hex of a socket, an offset combination wrench directly on the plug, an open end wrench on a socket, etc. Some plug sockets are taller than others which may let you use the ratchet or wrench easier.
Also, over the years I've had to grind the o.d. of a socket or chamfer it, or even turn the first 1/8" or 3/16" of the socket 1/16" or more smaller. Same goes for a combination wrench that you use on a plug - some grinding on the o.d. may help with getting the wrench on the plug.
On top of all that, the Nova requires that you remove one plug from the bottom, so don't be afraid to try that.
I use a Snap-On plug socket for several reasons. First I know these tools are expensive BUT there are times when nothing else will come close to doing the job, their spark plug sockets have a very good insulation grommet to hold the plug during installation and removal so it dose not fall out and get lost or hung up on something in the car and this grommet will help prevent the plug from getting cracked, they also have a hex portion where the ratchet attaches where you can use a open/box wrench or a socket instead of just a regular ratchet. Snap-On also sells what I call a 1/4" broke neck or swivel head ratchet that your local Snap-On tool dealer will for a fee put you a 3/8" head in this 1/4" ratchet for much more versatility. A ratchet fixed like this will become one of your favorite tools especially if you are running headers. The cheaper sockets are a lot thicker due to the inferior metal used and just will not fit in some tight place around our exhaust manifolds and headers.
I really don't have a favorite tool for this type of work.Sometimes i combine either some Mac,Snap-on or Craftsman tools and go from there. # 7 and 8 cyl. plugs are the ones that give me a hard time. The others are a piece of cake. :anim_25: :bowtieb:
I raced for many years with different setups. The last 10 years I raced, we ran a nitrous car and I checked/changed the plugs after every pass. I had a bunch of modified sockets that had sides cut out, shortened, nuts welded to them and all kinds of crazy stuff. Didn't need any of that stuff after using the spark plug sockets from powerhouse.
