Default MacGyver approach for pulling heads

I'm about to acquire a '33 21 stud that was rebuilt in the 60's but never installed. Until a couple of years ago, the owner would squirt a little oil in the plug holes and turn it over occasionally. I'm expecting the worst....my luck hasn't been the best lately so the engine will probably be stuck. I plan on backing off the head nuts a couple of turns,remove the plugs,find a cylinder that's close to firing position, squeeze a firecracker inside the cylinder and touch it off.I know... I don't think it'll work either.But I'll do it anyway.Whadda' you guys think? I've read most of the threads on this topic but I'd like to try a different approach.

No.

Firecrackers are for disturbing the neighbors!

I would think that if it was put together and not run that the heads would come right off---even be so nice that the gaskets can be reused (I have reused the headgasket on my A 3 times)

if he has been oiling it for 40 of the 50 years it was sitting it should not be stuck

Doesn't sound like something that would work to me (depending on what size of "firecracker" you are talking about). Be sure and post the outcome, should be interesting.

Silly question but, before applying the explosives, have you tried to turn it over?

No (39 topless). That's not a silly question. But thank you.I'll try that first with ATF and acetone. The way my luck has been going lately (failure to come to a complete stop at a stop sign,$345,A failed dental implant $3800X2,Grub worms in my lawn,Jury duty notice and the list goes on) it'll be stuck.Trust me.

It will all stop some day, so enjoy each one that you are vertical . Others go thru much worse. Be happy and work on old cars.

If the engine has been rebuilt in the '60s and not run, just why do you feel the need to pull the heads?

I agree with Franklin. Why not squirt a little oil in the holes and see if it turns over. But just in case it doesn't,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Hide all your knives and ropes first and any other deadly utensils first.

if its been oiled, its a runner. at worst, some sticky valves, or i've had just the oil pump stuck, only to find out after a complete tear down, or once broke the pump forcing it

There is no reason for me to keep the engine.I'll sell it eventually but I want to make sure it's a good one. I want to pull the heads and intake for a quick visual. Then take it to a machine shop so they can give it a good going over. These early flatties are becoming scarce as many of them were tossed when swapped out for the new more powerful ones.I could probably get it to run as is but would rather spend a few bucks and make sure it is as good as it can be before I sell it to someone building their dream car.

If you are planning to sell it won't this just add to the cost to recoupe? Gaskets, machine shop, firecrackers, and hospital bills?

If you put one in each hole, just remember to light them in the correct firing order.

If you have ever used air pressure in a spark plug hole to hold valves in place to change springs, (OHV) you'll know the first thing to happen is for the piston to go to bdc.. That will happen long before the head comes off.. Speaking of that, why not just use air???

That is not as crazy as it sounds.
There was a vintage aircraft engine that was started with a blank shotgun shell.
