I have a set of hipo manifolds and wondering if they are original.They do not have a date code on the back. I'm thinking maybe early repos? Anyone familiar with these numbers?
Thanks,
Randy

If I remember right, the small round bosses pictured (the three on each manifold) are also visible on the inside on genuine hipo's, but not repo's.
You remember correctly. The ones on the inside should be removed for performance. I don't mean maybe. They are in the worst possible place for flow.
