Yes. You’ll be able to do companion cylinders by the pair. When one is on TDC the other will be in valve overlap(both intake and exhaust valves will be open slightly and those rockers will have no lash.

You'll want to have a breaker bar on the crank socket and braced against something. Once you pressurize the cylinder, the piston may want to go down unless you have the rod perfectly straight top dead.

I absolutely do not understand why you’d want to jump over to #6 next since that cylinder has the valves in active overlap. I’d much prefer them static and I’d do #1 at TDC of the compression stroke followed by #8, etc. all methodically in 90* increments. BTW, if it’s a solid or solid roller, take a cold lash measurement before removal so you can put it back extremely close to what it was.
