It sounds like you're being careful and taking the right steps. FWIW - The F(Z)J80 engine (either 1FZ-FE or 3F-E) will have different compression numbers than a 2F.

Between 4 2F engines - '76, '78, '83, '87, I've never seen more than about 123 dry for a compression value. Most were 116-118 for a healthy engine at 7000' elevation (my house). These were all stock engines with no performance mods and one was rebuilt.
