Wilma, it does. Thank you. So my 05A car would be best with an April dated pair of heads.

I'm sure there were common production dates for the heads...might help to compare with another May built car. Sully has a May L78 Nova...maybe he has the dates from his cylinder heads.

As a general rule...30 day window is ok...there are exceptions. Keep in mind that by May of 70 most of the 291 heads were being used for the L78 Nova and LS6 Chevelles...and a few for the L78 Camaro, though I'm not sure of the production windows for those cars.
