There is a tool made to pull the engine forward as much as the engine mounts allow for better access to the rear bank of plugs on these engines..

I would not pull the engine for just four spark plugs to replace, As you can see from the first post the picture of the plug I pulled out. It was very clean.

Getting to know your vehicle is my passion to understand how it operates. One starts to change things. I was curious if the maintenance of the car is up to standard. When I received the car I checked all the fluids, belts, tires etc...
The engine was main concern. I wanted to see the condition of the spark plugs. Looking at can tell me how the car ran, If there was any oil leaking into the plug.
After I pulled one plug to look , I found normal wear. Nothing that looked suspicious. Here's what all four looked from the picture.

I gapped only four, Because going to the passenger's side was so many obstacles to remove to get at the other four. I attempted to remove the spark plug covers but was restricted due to the heater core hose, amongst other things like the distributor cover which was a big deal to reposition back. I thought I would need a better plan to tackle the other side.
So I hope this would answer any questions " Why did you go and try to change what is not broken" My answer is Because " I gotsta to know".......
My '67 small block has factory air, so I am familiar with the challenges you encountered. I have found that replacing spark plugs on the passenger side is very difficult to do from above. Access is better from underneath. Even from underneath, the two front plugs on the passenger side are difficult to access.

However, there is a trick that I learned many years ago working on my Dad's 66 Impala station wagon with factory A/C. Those two front plugs on the passenger side are easy to access if you take off the right front wheel. If you push aside the rubber splash shield on the inner fender, there is almost a straight shot at those two plugs. Aside from the hassle of removing the wheel, the plugs are are very easy to access.

That's exactly how I did it, for years, on my '67 with factory A/C. While it was up in the air, I changed the other six from the bottom...so much easier. Although, 1 and 3 are easy no matter how you decide to change them.
