Are they dimensionally the same - and are they interchangable ?

Bought a new set of rings of ebay for a cosworth and a set of ae ones turned up which I am pretty sure are for a 2 litre pinto

codes are s101 R25256 Ford 3,5748"/90,800

The box even had a price of £39 + vat tipexed out

I paid £60 believing they were £99 rings

have I been conned or is this another case of us paying cosworth tax on identical parts like the INA lifters ?

Can only people with 100% knowledge please answer as I will have to front the seller if they are not suitable in a cosworth engine.

cheers
