Is that correct? I just finished searching the entire net and I found 1/4-20 x 3/4

Absolutely. Ran the screw into a die. It's way smaller than 1/4-20.

35mm may fit on the header side (not sure) but the OEM ones are 20mm.
35mm is one long a$$ screw...

I just saw that your car (DLF) is a 95. Mine is a 90.. are the flanges thicker on the header side on the 95?

Bolts are longer for 95 valve covers. You can't use the same bolts if you switch to early style 93 steel valve covers. no measurements because they are on the car right now though.
