That compression tester is expensive and I don't think it has the right size adaper with it. The thread on out plugs IIRC is 12mm Gunsens sell a an optional 12mm adapter. That kit is designed for cars I think.
Have at look at this

Just double check the plug sizes with them that come with the kit as it does not give the sizes.
or this one, a bit more expensive but has an M12 adapter with it.

Or just borrow one.
I'm not sure on that valve spring compressor, yet again being Halfrauds I think it's designed for cars. It looks OK for the job, but I'm unsure of the dimensions of our heads and that jaw might be too big for the spring caps. Have a measure up on the heads on your old engine.
There's also these style compressors as well, that work a bit like a G clamp.

The grinding stick and paste is spot on mate and cheap enough.
Your parts list looks good, but you could save a few penny's. Do you really need a exhaust gaskets or tensioner gaskets. IIRC your exhaust gaskets are relatively new and if you have a bit of gasket seal knocking around then smear a little of that around the base of the tensioners and a bit on the thread.
The only other thing you may want to account for is valve shims. You may need a couple. Benny has the shim kit or as your heads will be off, do your measurements/sums and buy whatever size is required rather than a whole kit.
