Indy 360-1 Cylinder Heads

I have talked to Schoenfeld
they don't make a header flange for the Small block indy.
The w-2 is the closest

Also talked to Russ at Indy- custom header
asked about the 360-1 vs 360-2 if they were cast from the same type mold (only a port difference) and could the square be opened up to the W-2
Never got an answer> Guess, I'll be doing some sonic mapping/ testing this winter

center ports are problem area.

I'm going to make a new flange for the center, and move the center pipes closer, on the w-2 headers I have

If I could start over, I would try a W-9 or a W-9 (lite) flange
