Your customer,.....cool.
Don't know much about Delkron, other than motorcycle parts.
Please tell me about you and Cometic and why their better ?
Do you/them make FE tube header gaskets ?
I need to know so I can order some gaskets.
Ford 428 FE Intake, water pump, timing cover, maybe
oil pan (and header if Cometic makes them) from either MAHLE or Cometic.
