Yes there are other factors to the game also.
For instance I have heard that Pontiac aged there cast iron pieces long before machining them, and here once again it would be nice to know if that where true.
Other things matter much also.
I have ground on many a Ford head to find such porosity that plans made to port them to a certain level of air flow had to lowered, and I have just found this condition in a AMC head I just ported.
So then to me with a condition like this, one has to wonder when, other then cylinder walls and lifter bores ware wise how much a good quality iron matters if there’s inclusions everywhere.
