hmm i shall compare to the bluetops ones i have......
i wonder if they are forged ones. repco do ACL pistons and i think they have a listing for 4agze ones, but they are bloody exspensive and afaik not as good as genuine ones
Fluck me silly with a wet spoon.
I must be previlaged to have only operated with aftermarket high compression pistons and of course the odd 20 valve or seventeen. Those standard pistons are UUUUUUGly.
The answer is Helmholtz!
