1967 exhaust manifold date question

[Mark U.]

my 67 427 car has many parts that are dated early may-i need to buy a pair of exhaust manifold for this car-question is how close do i need to come from the dates of the other engine parts-30 days-60 days or 90 days or does the dates on the manifolds really matter.

Thanks Mark

Mark,

I would suggest that you follow the NCRS six month rule.
