Are the exhaust outlet flanges flat or tapered to use a 'donut' spacer/gasket? The C3SZ manifolds used the tapered/'donut' spacer while earlier ones typically were flat.

As for the engineering number you found, to confirm what Kultulz sez, those were used '58-early '60: while researching part numbers for Vintage Thunderbird Club International's 1958-1960 Original Factory Specifications manual 15 years ago this drove me nuts!! Thankfully I have a copy of the Master Cross-Reference Parts Catalog with the 7-digit all-number engineering numbers and corresponding Parts & Accessories (P&A) prefix-basic number-suffix ID numbers to compare against. What I found, if I remember correctly, was that the last digit of the engineering/production casting number might be off by 1 or 2 numbers compared to the service part's P&A and corresponding engineering number.
