@MatthyJ... Yeah they sit so well with the 6v71 and it hides the ugly way it tapers. My 6v71 is from Dyers so I can ask them but I doubt they will know. I can see these were fabricated by someone and would love to know who.??
They just work so well with a V series blower and is very different. Plus I prefer the smooth tops over the rib kind. The guy on instagram that owns them will not msg me back.

@Da34Guy...Yeah I know about your valve covers I've been following the treads on the H.A.M.B. There is a fellow on there that has a set but he will not tell me how much he wants but If its over 1000 I prefer to get them custom made like the ones above which would work better for my car as its not a vintage hotrod but more like your 68 Camaro...

Does anyone know who I could approach to ask to get a custom set made?
