87 22r spark plug recommendations
running 1987 22r with 131000 miles. truck has 31 x 10.0 firestone destination ats under it. cat has been removed , egr bypassed , vacuum lines replaced , air filter and plugs new timing set. I still have no power on a hill . I know the tires rob power , and it is only a 4 banger . people have told me to put a hotter plug into and toss the copper plugs . does anyone have a recommendation for type of plug and maybe a hotter coil ?

I use NGK BPR5ES plugs in my 4 cylinders engines
A hotter plug just moves the electrode closer to the piston
It is a 4 cylinder in a heavy truck
I not sure what kind of performance your looking for. Just what are you comparing it with
If you want power in the hills changing the gear ratio is about the best bang for the $$$$

-Have you checked your timing ?
- Vaccum advance on the distributor?
-valve Clearence?
Also with 31s you should not have a dramatic loss of power compared to the 28ish factory size tire

Different spark plugs are unlikely to solve your problem unless they need replaced anyhow. Get NGK V Power or go to a Toyota dealership and get the OEM plugs. They are different than the Denso plugs available at parts stores.
If you use anti-seize don't use much and don't apply any to the last couple of threads closest to the center electrode. When applied correctly it's said that you almost can't tell it was used when you remove the plugs or grounding issues can occur.
The classic
"I just discovered anti-seize and dielectric grease".
Have you done a compression check?
