Factory HP logs for B body cars can fetch a good dollar.
Year one sells repros for even more money.
Keep them.If you-or anybody else- ever go back to
stock you will be happy that you did hang onto them.
FYI,the right manifold also fits C body cars,so there is even more demand for that side.
I should know.Every C I seen in a yard that was HP log equipped was raped of its right log to a B body resto..
