SBC heads

Does anyone know if any of the OEM centerbolt valve cover style heads came with angled spark plug holes? I want to run a set of Speedway's Tru Ram style manifolds on them. The Speedway site says that they work with angled plugs. I also want the centerbolt valve covers for better sealing.

 

95 & earlier production heads were straight plug.

G'day, All the center hold down heads I've seen have been straight plug including Vortech and lt1.

Does this help?

Perhaps they should say, "ALSO works with angle plug heads". That's not leading to confusion is it? They work with BOTH. Butch/56sedandelivery.

 

Read it again... thanks!

So no one has seen ZZ-4 heads? Were also used several years on Corvette. I'd call them 'production'.
