We just ordered the MK4 complete kit with 302 headers. Will these work with the BluePrint 427 ci small block engine?

No. You need to get the headers for a 351 block. But also make sure it has standard height exhaust ports.

Also, for the record, I see you posted this in the "Ask Factory Five" forum. You might get an answer. But maybe not which is why I posted. You're way better off calling Factory Five. Or emailing if you have an established contact.
