Hi,
trying to ID these heads which are on a 1971+- replacement block. They seem to have a 6 digit ID # when all the ones I saw on Moretec had 7. Not sure if the first 3 digits are 399 or 389 or other.
Thx
Those are the 3991492 heads. They are Service Replacement heads for 1969 - 1972 350 with 2.02 intake valves and 1.6 exhaust valves.
Good info thanks that fits with the engine narrative though the owner thought is was a short block swap that now seems like a long block swap. May have to wait until the head needs to come off to poke around and know for sure.
