I studied them for an hour picked what I thought were the best two, loaded them in my red wagon, wheeled them to our trailer. And went and told the superstock racer to go get the other two.
This was when the Etown race was in late July.
Well come labor day weekend. We are in the tech in line at Indy and talk to the superstock racers Driver. He asks if we put the heads on the car yet, and told us they helped a bunch. But it took a long time getting the headers on. We hadn't done anything with that set of heads . But had a set with an Identical casting number on the car.
It did not come to mind that the superstock team had changed engines in half an hour when needed. Mere headers should not have phased them a bit.
Well that was back when all class winners went to the barn. The superstocker had their head off and on the bench, so we rushed to get ours up there. Nhra hated to do Hemi's because they had to fill the burrette up twice for the 168cc combustion chamber and the guy that was doing the heads at the time was a good guy. I took the head up and was looking at the head on the table it seemed to have "slightly" smaller intake ports than our head Then I wiped the sweat out of my eyes and saw I was looking at the exhausts.
Then the stock and superstock heads were the same except for valve springs and retainers. Those exhaust were almost as large as my intakes plus the bolt holes were moved. That was why the trouble with the headers.
When I saw this I knew I couldn't put our head down or they would have bounced the other head. So I told them I had to go ice our head down, and brought it up an hour later. Everyone passed and we all had a good race.
But then and there I knew it was over. We quit the following year.
