Stuck Piston Rings

[Enoch]

Hi folks, have reached a bit of a cross roads in my build. I think I have stuck piston rings on a couple of cylinders. I can't be certain without taking the heads off and maybe removing pistons - if I do take the heads off I am in for about £150 for gaskets and a lot of messing about. I would also need to make half a dozen service tools (liner hold down plates, head removal tool, chain tensioner puller and adjuster release tool).The Jag engine is known for sticky rings (no rude comments please) a common cure is an "Italian tune up" but I can't do that until the car is driveable, it may not fix the problem and then everything will have to come apart to get the engine out and get at the offending rings.
I am trying to get a consensus as to the best way to go with this, favourite at the moment is to run a compression test, dump some auto trans fluid down the offending bores, leave it for a week and then see what the situation is from there.
It needs new oil anyways so it does not matter if atf finds it's way in to the sump.
Anybody got any thoughts on this subject??
I really want to avoid a full engine strip if I can but don't want to end up with having to pull the engine after it's first test drive.
Thanks in advance.
Dave.
