BSA A65 tappets in Nortons

These lifters were the best choice I made building my small block Ford.
Pulled HARD at the top, very streetable down low

As far as I can tell, in a US English made table it's only Aluminum and Lanthanum (57). In some British-made tables there is only Lanthanum.

"Flat tappet" commonly used to differentiate the type of sliding lifter used BEFORE the advent of roller lifters.




The nomenclature carried on/mutated from flathead days, when the adjusters for valve lash were on the tappets.
