Which Headers ?
 

I am part way through installing a ZZ4 crate motor in my 59 Apache.
It has stock front suspension with Posies 3" drop front springs and I am also adding the CPP Toyota style power steering at the same time.
Everything was going ok - slow but ok !!

But, Header fitment seems a little tricky, I have a set of Patriot shorty headers which hit the steering box, as a temporary measure I have purchased a set of Speedway's Rams Horn manifolds - but there is a slight port mismatch with these.
People running this engine/exhaust combo on the Corvette forums seem happy with the way their cars run so maybe all is ok.

Anyone running a similar combo ?
Your thoughts ?

Wouldn't original or even reproduction factory style exhaust manifolds with the 2 1/2 inch diameter outlet look, fit, flow, as well or better than the Speedway rams horn headers? They were good enough for the hi-performance Corvettes.

Still allowed and used in Stock drag racing classes, and for most engines with relatively mild cams they flow just about as well at normal operating RPM.

The large aftermarket ram's horns aren't bad for a mild engine. You might get better port alignment with a set of 92~ish Vette factory manifolds.

Pacesetter also makes a set of shorties that will probably fit those ports better. P/n 70-1340
