322 valve lifter question ('54 or '56)
So a while ago I finally bought my first Buick (https://www.teambuick.com/forums/sho...w-from-Belgium).
Now I have had some issues with lifters. getting the correct ones to be precise.
When I bought my '54 I knew it had some bad lifters, so I took it apart.

Now, I am 100% certain this is the engine the car came from the factory with back in 1954 because I have the original salesreciept that has the cars VIN and the engine VIN.
I ordered some new lifters at a local shop and he got them from the US using the engine VIN as refference. But after 2 weeks I got what I believed to be 'wrong' lifters.
LEFT = NEW 'WRONG' LIFTER / RIGHT = 'ORIGINAL' LIFTER

So I went and complained, he would see what he could do, and in the mean time I ordered some lifters directly from a classic Buick-only shop in California (wich where specified as '53-'55 lifters).
After these showed up they turned out to be thesame 'wrong' shorter lifters I had been send before.
Now the guy from the local shop had ordered other ones after measuring my 'original' lifters, and had been send what apparently are '56 Buick lifters.
TOP = NEW 'CORRECT' / MIDDLE = 'ORIGINAL' / BOTTOM = NEW 'WRONG'

The guys he got them from in the US said a common swap back in the day was to put '56-'57 heads on the older '53-'55 engines for a little more horsepower, and that was probably what had happend here.
But I've read in some places you cannot use a '53-'55 stock cam with '56-'57 lifters due to wear.
Now some of my lifters where pretty bad, and one camlobe was also worn down kinda bad in my opinion.

So to get down to the actual questions here:
1. How can I check I have '56-'57 heads on my engine?
2. Is this wear just from running with a couple bad lifters? (and bad modern oil, I've got proper thicker oil to put in it)
3. Can I run these '56 lifters with the original cam or not?
4. Incase 3 =NO, would the best fix be to buy '54 pushrods and put in the '54 lifters I have OR put in a '56 cam?
Thanx alot,
