A $20 dial indicator will yield a dead accurate timing stretch reading, I'd recommend going that route. Akin to using a timing light to time a distributor.
It is possible to have a chain with very little stretch on an old engine-if they regularly maintained it or if it was replaced in the past.
If I remember correctly, each tooth advanced/retards your timing ~18° which is way too much

He would need a holder for the DI + some sort of extended rod on it to reach from above the cam down to the top of the valve keeper. There is no room for a DI next to the cam and directly above the valve. I've been wanting to check my chain stretch using this method but no DI I've seen has a long enough rod.
From what I've read here, people are fabricating there own extensions for this. If I'm wrong about this, please post a photo showing how it's otherwise done.
