The ORIGINAL header bolts on these cars were specially made for Detomaso.
They are SAE 3/8-16 threads but the bolt heads are METRIC!
Of course you can use regular header bolts that are cheap from just about anyone. Mr.Gasket for instance.

Interesting. 2 years ago I purchased a set of stainless Tri-Y headers for my 66 Mustang (289) and they came with cheap Chinese header bolts that had SAE threads and metric heads - discovered that after having my SAE wrench slip, just as you describe!
